Butterfly Valve EUROSTOP Manual type - Reinforced version (Abu Dhabi)Flanged Butterfly Valve (flange-flange) with joint in the automatic but-terfly (JPA) with double eccentricity and long spacing between theflanges.Ductile iron body and butterfly covered with blue epoxy powder 300microns mini.Range from DN150 to DN2000mm for pressures of PFA10 to 25 bar.Field of applicationButterfly valves are isolating valves used on water supply networks, in the interconnections of network, in the factories, in pumping stations, on the general networks and on the fire protection networks in the industrial sites.Butterfly valves are compatible with drinking water and raw water with grid filtration. They will be installed on water networks in factories, in valves chambers or buried.Their main advantages are:•Low pressure loss•Good performance thanks to the choice of the materials, the coatings and the design•Easy operation per mechanism of the worm type/without end•Mechanisms equipped with a standardized flange carry-accessory for buried version and motorizable version RangeThe EUROSTOP butterfly valve is available in different configuration: manual, buried service, motorized and motorizable (for this three last configuration see the specific TDS).References Manual TypeMaterial and coatingValve equipped with 4 holes for the lifting of the valves DN>600. The gear box of the mechanism is in ductile iron FGS 400-15 type.Dimensions and massManual Version PN10Manual Version PN16Manual Version PN25Gearbox type and handwheel Manual type PN10Manual type PN16Manual type PN25Applicable StandardsHydraulic testEvery single butterfly valve is subjected to hydraulic final test with the purpose of verifying the accordance with the prescrip-tions ISO 5208:•Body test at 1,5 time the PFA (open valve);•Seat test at 1,1 time the PFA (closed valve).Product test•Control of manoeuvre torque (MOT and mST) as defined in the EN1074•Control of coating: test of thickness, holiday test, impact test, MIBK testConformity to the standardsProduct:•EN 1074 – 1 and 2•EN 593•ISO 10631Plant test:•ISO 5208Flanges dimension:•ISO 5752 series 14Flanges drilling:•EN 1092-2•ISO 7005-2Suitability for potable water:•Italian CM 102 of 02/12/78•Conformity to foreign norms: KTW (Germany), WRC (U.K.), ACS (France)MarkingOn the body like EN19:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Type of ductile iron;•Manufacturer’s logo;•Model code;•Fusion date.On the label like EN19:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Maximum operating pressure (PFA);•Closing direction;•Model code;•Manufacturing order, Order confirmation;•Manufacturer’s logo.On the disc:•Nominal diameter in mm (DN);•Nominal pressure in bar (PN);•Type of ductile iron;•Manufacturer’s logo;•Model code.The marking of the valves manufactured by Saint-Gobain refers to the EN 1074-2 and EN 19 international standards. Markings are either integral markings, cast in the body, or markings made on plates, securely fixed to the body, in accordance with the EN 19 standard specifications.Valve selectionThe butterfly valves are generally used as isolating devices type on/off. In some particular case, in which there’s low differ-ences of pressure and low flow rate variation can be used like regulating devices, considering the hydraulic parameters necessary to avoid the cavitation risk.To do the right dimensioning of butterfly valve it’s necessary to know the followings parameters:•Upstream hydrostatic pressure (that is the hydrostatic pressure with valve in closed position)•The maximum speed in water pipe (generally expressed in l/s) or the nominal diameter and the project flow rate from which it is gained the speed V=Q/AMoreover it’s necessary to control that the maximum speed in water pipe have to be equal or inferior to 5m/s, and the exercise temperature have to be between 0°C and 40 °C.Hydraulic featuresThe head loss Δh are variable in function of valve open degree and can be calculated with the following expression:with Δh = head loss (m), ζ = head loss coefficient (dimensional), v = nominal speed (m/s), g = 9,81 (m/s²)The head loss coefficient can be estimated from this diagram:Determinates the head loss Δh it’s possible to calculate the flow rate Q in m3/h with the following expression (the same expression can be used to, having the project flow rate Q, to determinate the head loss Δh without using the head loss coefficient):in which 10,2 is a corrective factor in meters, and Kv is the flow rate coefficient in m3/h, determinable from the following diagram in function of valve open degree:Example: Valve DN600 mm - Δh = 3 mFrom the diagram with valve open to 100% the coefficient Kv is 20000 m3/h. Using this date in the flow rate expression:Otherwise it’s possible to calculate the head loss with valve completely open, having the project flow rate Q, in function of DN, using the following diagram:CavitationIf the butterfly valve is used only like isolating device there’s not cavitation risk.In the particular case in which it’s used like regulating device, this can be possible only respecting the following parameters:•The valve open degree have to be between 30° and 90° (valve completely open)•The downstream pressure P2 have to be: P2 ≥ 0,7 .P1 - 2,8 with P1 upstream pressure.Instructions for useStorageThe butterfly valve will have to be held (if possible) in covered places, the most possible protected from the sun (maximum allowable temperature 70°C in accordance to EN 1074), from the rain and generally from the atmospheric agents. Moreover it will have to be avoided that the seal of the same air valves come to contact with powder or earth.InstallationThe butterfly valves are generally installed with retaining ring mounted in the opposite way respect to the direction of flow rate to permit the substitution of gasket without dismounting the valve from pipeline. In any case it is possible to install the butterfly valve with flow rate in opposite direction and also, if required, in vertical position. We recommend to install the butterfly with the operating device on the hydraulic right side of pipeline.It’s possible to install the butterfly valve both in chamber valve that underground (choosing the right configuration).We recommend to insert a dismounting joint for the operation of maintenance.MaintenanceThe butterfly valve does not require a particular maintenance, all parts subjected to wear are perfectly auto-lubricating. In any case, if for a long time will be not used, it is necessary to evaluate the functioning of valve doing (at least one time for year) some manoeuvre of opening-closing.All the maintenance operation have to be do after the total emptying of pipeline (no flow rate and pressure) to avoid every risk to the people during this operation.In presence of particularly exercise condition or damage due to external cause, it will be necessary some maintenance operation. In this case the particular shape of EUROSTOP butterfly valve permits the simple gasket substitution without the dismounting of valve from pipeline (if the dismounting joint is present).AccessoriesTo adapt the butterfly valves to the different exercise and installation conditions required, they can be equipped with particular accessories used in combination with control devices: please refer to data sheet for accessories.The technical features in this document are not contractual and can be changed without preliminary notification due to the continuous technical progress of product.。

手动阀门与自动流量限制阀门说明书

MANUAL VALVES VS. AUTOMATIC FLOW LIMITING VALVESydronic system balancing is an important part of the HVAC industry. Without hydronic balancing, some coils in a system have too much flow and other coils don’t have enough flow; the building isn’t “balanced.” An unbalanced system can lead to excessive occupancy complaints as people are either too cold or too hot in the building.Many engineers focus on carefully selecting energy efficient boilers, chillers, and terminal units. However, without proper flow through these units, their efficiencies and heat transfer capabilities are altered. The problem is exacerbated as the pressures change in the building’s hydronic system, as changing pressures have a direct impact on flowrate. Q=Cv√∆P) While the industry accepts that pressure changes cause flow changes which then causes heat transfer changes, many engineers still accept manual balance valves because the INITIAL unit cost is less than automatic or pressure independent valves. But is initial cost all there is to consider? Automatic & Pressure Independent Valves -the cost effective option over Manual Balance ValvesThe procedure to manually balance a system is very labor intensive. The pressure drop across each valve is measured and a ball or plug is adjusted to bring the pressure drop to design pressure. Each time a valve in the system is adjusted, the flow through the other valves will change including those previously set because of the pressure change. Hence, the previously set valves must be reset, which in turn affects the flow through the other valves...and so on. In a large system, a minimum of three balances per valve is generally recommended by ASHRAE and NEBB.Contractor price for ¾” manual balance valve with memory stop: $35.Cost to balance three times total: 20-30 minutes @$125./hr: $42.00 to $62.50 On the other hand, each automatic flow limiting or pressure independent (PI) valve is self balancing as soon as the pump is turned on. The only labor required is for flow verification. The pressure drop across each valve is measured by using the ports provided on the valve body. As long as the PSID is within the control range listed on the valve tag, the flow, which is also listed on the tag, will be within plus/minus 5%.HContractor price for 3/4” automatic valve with isolation valve: $60.Cost to verify ﬂow: <5 min @ $125./hr: <$10.Manual = $77 to $97.5Automatic = <$70It is true the initial cost of a manual valve is less expensive than an automatic valve, but once labor to balance the valve is taken into consideration the total cost can be considerably more. More importantly, once the system is live and pressures start changing an automatic or PI valve will maintain the design flow in spite of system pressure changes. A manual valve will have an increase or decrease in flow as the pressure increases or decreases.Buy Fewer ValvesSystems utilizing automatic flow limiting or PI valves require far fewer balancing valves than systems that are manually balanced. Figure 1 shows a schematic of a system serving 18 heat transfer (heating or cooling) coils.Figure 1.The manual system, shown above, requires a total of 27 valves whereas the automatic system, on the right, requires only 18 because it does not require the “partner balancing valves” (shown in red) on the risers and the branches.As each terminal unit automatic flow limiting and pressure independent control valve isself-balancing over a wide differential pressure control range, the flow through the risers and the branches is also automatically controlled (balanced) without the use of additional valves.Using 18 valves instead of 27 manual valves is approximately 1/3 savings in initial product purchases. In our previous example that is 27*$77 to $97.5 or $2,079 to $2,632.50 in manual valve costs. In comparison the automatic system costs 18*$70 or $1,260 in valve costs which is a substantial savings.The elimination of the manual partner balancing valves on the mains, risers and branches in turn eliminates the head loss through them. Hence, the system head loss is reduced which lowers the pump head requirements.System Stays Balanced Even During Reduced Load ConditionsNo coil will starve when saving money by variable speed pumping. However, reducing the total water flow does not mean that all the coils in the building individually need the same reduction in flow. For example, on a typical spring day at 1:00 p.m., the total chilled water requirements of an8-story office building will generally be much less than on a hot summer (design) day. However, the air-handler serving the filled-to-capacity cafeteria, on the first floor, will require almost 100% (of design) chilled water. A building with automatic flow limiting or pressure independent valves will give you this diversity whereas one with manual balancing valves cannot.Figure 2.The schematic at the top shows the design load condition. The system operation point, at design load, is at (say) 125 feet of pump head. The head loss across the various elements (which adds up to 125 feet) for the cafeteria circuit, is as shown. Since the cafeteria is on the first floor, the head loss through the risers is negligible and is ignored.Please note, for design flow at design head, the head loss through the manual balancing valve is the same as that through an automatic flow control valve (86 feet).If this is a manually balanced building, as shown in Figure 3 on the left side, valve MBV #5 would have to be added and manually set. Howev-er, doing this would change the flows through existing valves MBV #1 through MBV #4 and they would also have to be reset. Similarly, upstream branch/riser balancing valves (not shown) may also have to be reset. The resulting labor cost can be significant.If this is a building with automatic flow control valves, as shown in Figure 3 on the right side, you would only have to add valve AFLV #4. Because these valves have wide control ranges, they would all automatically self balance to provide the required flows. No labor would be required to set the new valve or to reset any of the existing valves.Figure 3.The schematic in the middle shows what happens when system flow is reduced (by lowering the pump speed to 52%), if the system is manually balanced. At the lower speed, the pump head will be smaller as will all the pressure losses. Since nothing else has changed in the cafeteria coil circuit, the head loss through the various elements will decrease proportionately and now add up to 65 feet instead of 125. Since the head loss through the manual flow control valve is reduced to 44.7 feet and since flow is proportional to the square root of the head loss, the flow through the manual balancing valve (and the coil) is reduced to 72% (square root of 44.7/86). There is NOW a flow deficit of 28%.The schematic at the bottom shows what happens when system flow is reduced by the same amount if the system has automatic flow limiting valves. Again, the pump head decreases to 65 feet. However, the head loss distribution is not proportional. Instead, the cartridge inside the automatic flow control valve moves by a precise amount, to absorb only 26 feet of head and keeps the flow at the required 100%.With the automatic flow limiting or pressure independent valve, there is no flow deficit at reduced system flow and reduced pump head.(Note: In all three schematics of Figure 2, all losses in the pump room are ignored for clarity of discussion.)Building Renovation Does Not Require Hydronic System Rebalance Very often, space renovation in an existing building also changes the heating/cooling requirements of that space. For example, an open office area that is converted into a large conference room will require more cooling due to the additional sensible and latent heat from the people. This may result in an additional fan-coil unit for the conference room. Figure 3 illustrates this scenario for a Manual vs. Automatic system.Griswold Controls designed the first balance valve in the market in 1960, years before the first manual balance valve was designed and manufactured. The all stainless steel flow limiting cartridge is a standard in the industry because of its simply elegant design. Above its control range (blue colored area in Figure 4), the cup will move all the way in, exposing the minimum orifice area. In both cases, the cartridge will now act as a fixed orifice device, varying flow based on the out-of-range differential pressure.You do not have to worry about the cartridge ever shutting off the flow completely because a minimum orifice area is always open.C U P P A R T I A L L Y O U TCU P F UL L Y I N C U P F U L L Y O U T Below the control range, the cartridge acts as a variable flow device, allowing flow to vary below the rated amount.Above the control range, the cartridge acts as a variable control device, allowing flow to vary above the rated amount.Within the wide control range, the cartridge modulates in response to pressure differential changes to maintain a fixed flow rate within ±5% accuracy. Figure 4.2803 Barranca Parkway Irvine CA 92606 • Toll Free: 800.838.0858 • 1/18F-5586How does an Automatic Flow Limiting Valve Maintain Design Flow?When the differential pressure across the cartridge falls below its control range (pink colored area in Figure 4), the cup will come all the way out, exposing the maximum orifice area. Similarly, if the differential pressure across the cartridge rises。

In some particular case, in which there’s low differences of pressure and low flow rate variation can be used like regulating devices, considering the hydraulic parameters necessary to avoid the cavitation risk.To do the right dimensioning of butterfly valve it’s necessary to know the followings parameters:• Upstream hydrostatic pressure (that is the hydrostatic pressure with valve in closed position)• The maximum speed in water pipe (generally expressed in l/s) or the nominal diameter and the project flow rate from which it is gained the speed V=Q/AMoreover it’s necessary to control that the maximum speed in water pipe have to be equal or inferior to 5m/s, and the exercise temperature have to be between 0°C and 50 °C.Hydraulic featuresThe head loss Δh are variable in function of valve open degree and can be calculated with the following expression:Δh = head loss (m)ζ = head loss coefficient (dimensional)v = nominal speed (m/s)g = 9,81 (m/s²)The head loss coefficient can be estimated from this diagram:Determinates the head loss Δh it’s possible to calculate the flow rate Q in m3/h with the following expression (the same expression can be used to, having the project flow rate Q, to determinate the head loss Δh without using the head loss coefficient):In which 10,2 is a corrective factor in meters, and Kv is the flow rate coefficient in m3/h, determinable from the following diagram in function of valve open degree:Example: Valve DN600 mm - Δh = 3 mFrom the diagram with valve open to 100% the coefficient Kv is 20000 m3/h. Using this date in the flow rate expression:m3/hOtherwise it’s possible to calculate the head loss with valve completely open, having the project flow rate Q, in function of DN, using the following diagram:CavitationIf the butterfly valve is used only like isolating device there’s not cavitation risk.In the particular case in which it’s used like regulating device, this can be possible only respecting the following parameters:• The valve open degree have to be between 30° and 90° (valve completely open)• The downstream pressure P2 have to be: with P1 upstream pressure.Instructions for useStorageThe butterfly valve will have to be held (if possible) in covered places, the most possible protected from the sun (minimum allowable temperature 0°C and maximum allowable temperature 70°C in accordance to EN 1074), from the rain and generally from the atmospheric agents. Moreover it will have to be avoided that the seal of the same air valves come to contact with powder or earth.InstallationThe butterfly valves are generally installed with retaining ring mounted in the opposite way respect to the direction of flow rate to permit the substitution of gasket without dismounting the valve from pipeline. In any case it is possible to install the butterfly valve with flow rate in opposite direction and also, if required, in vertical position. We recommend to install the butterfly with the operating device on the hydraulic right side of pipeline.It’s possible to install the butterfly valve both in chamber valve that underground (choosing the right configuration).We recommend to insert a dismounting joint for the operation of maintenance.MaintenanceThe butterfly valve does not require a particular maintenance, all parts subjected to wear are perfectly auto-lubricating. In any case, if for a long time will be not used, it is necessary to evaluate the functioning of valve doing (at least one time for year) some manoeuvre of opening-closing.All the maintenance operation have to be do after the total emptying of pipeline (no flow rate and pressure) to avoid every risk to the people during this operation.In presence of particularly exercise condition or damage due to external cause, it will be necessary some maintenance operation. In this case the particular shape of EUROSTOP butterfly valve permits the simple gasket substitution without the dismounting of valve from pipeline (if the dismounting joint is present).AccessoriesTo adapt the butterfly valves to the different exercise and installation conditions required, they can be equipped with particular accessories used in combination with control devices: please refer to data sheet for accessories.The technical features in this document are not contractual and can be changed without preliminary notification due to the continuous technical progress of product.NOTESaint-Gobain PAM Italia:- reserves the right to modify the products anyway fully respecting the Laws in force.- always use products fully complying with the European Directives to which the products themselves have to comply with.FOR ANY FURTHER POSSIBLE TECHNICAL INFORMATION PLEASE CONSULT SAINT-GOBAIN PAM ITALIA AND/OR OTHER PAM SISTER COMPANIES。
