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.。

The standard valve size range available is as follows:• 200 psi Standard BFV 2" to 12" 150 psi Standard BFV 14" to 36" • 285 psi BFV 2" to 24" Stockham 285 Butterfly Valve is also available with an ASME Class 300 bolt pattern for Lug bodies of sizes 2" through 12". Valve Design Features• The unique Stockham seat and disc design insures positive valve sealing while maintaining low seating torque. • All Stockham Butterfly Valve discs are precision machined to a half ball profile, providing a precise disc to seat relationship.• Stockham's cartridge style seat incorporates an elastomer bonded to a phenolic stabilizing ring, eliminating elastomer movement and reducing seat tearing or fatiguing due to bunching.• Stockham's basic three bushing design completely isolates the valve shaft from the body, resulting in increased control of the valve disc, lower valve seating torque, and longer valve life.• The Stockham cartridge seat has a much smaller massof elastomer than traditional boot seat designs, limiting seat swell and the accompaning variations in seating torque.Flange and Pipe Schedule CompatibilityThe Stockham RSBFV is designed to fit between standard piping flanges as follows:• ASME 125 Cast Iron Flanges (All Sizes)• ASME 150 Steel Flanges, Schedule 40 (All Sizes)• ASME150 Steel Flanges, Schedule 80 (2" to 10")• ASME 300 Steel Flanges, Schedule 40 (285 Lug,2" to 12" only).When using Schedule 80 piping, special care must be taken to make sure the valve is centered between the flanges to prevent damage to the disc edge when opening or closing. Gasket CompatibilityIn the Stockham butterfly valve design, the elastomerseat extends beyond the valve face and providesa leakproof seal between the valve and the mating pipe flange faces. Gaskets are not needed and should not be used when the valve is installed between standard weld neck or slip-on type flanges.Operating PressuresAll Stockham 200 Butterfly Valves are rated at 200psi bubble tight shut-off for sizes 2" to 12" and 150 psi bubble tight shut-off for sizes 14" and larger. Stockham 285 Butterfly Valves are rated for bubble tight shutoffat 285 psi.Product IdentificationEach Stockham valve has an identification tag attached to the valve body. Information on this tag includes the valve Series Number, materials of construction for the Body, Disc, and Seat, and the valve Pressure Rating.INTRODUCTIONSERIESBODYT:800-STOCKHAM • F:256-775-3860 • 31.2.3.4.5.6.7.8.Check the packing list against the valve received to verify that the size, material, and trim are correct.Check to make sure that the valve and operator were not damaged during shipment.When lifting the valve, take care to avoid damage to the flange faces, disc sealing edge, or operator.If the valve is to be stored before being installed, it should be protected from harsh environmental conditions.Store the valve with the disc in the “almost closed”position to protect the sealing edge and the seat.Keep the valve in a clean location, away from dirt, debris and corrosive materials.Keep the valve in a dry area with the flanges protected and on a suitable skid or pallet.Keep the valve in a cool location if possible, out of direct sunlight.Opening RotationThe Stockham valve disc can rotate 360° without damag ingthe valve or elastomer seat. The valve is designed toopen with either clockwise or counterclockwise rotation ofthe shaft.Valve RatingsStockham valves are intended for use at the pressure indicated on the nameplate attached to each individual valve. Check the valve operating temperature and pressure rating before proceeding with installation.4INSTALLATION RECOMMENDATIONSValve and Flange PreparationIf the valve and mating pipe are properly prepared for installation, future problems can be avoided. All valve seat and pipe flange faces should be free of dirt, grit, dents, or surface irregularities which may disrupt flange sealing and cause external leakage. The valve disc sealing surface should also be inspected to eliminate any dirt or foreign material that will adversely affect the operation of the valve.Installation PositionTo prevent damage to the disc and seat during installation,the valve disc should be slightly open but not extending beyond the valve liner face. Positioning the disc in this “almost closed” position will reduce seat interference and initial torque build-up during valve installation.In general, it is preferable to install RSBFV's with the shaftin a horizontal orientation. In this position, shaft and discweights are evenly distributed, minimizing seat wear.Additionally, any foreign matter which may accumulate atthe bottom of the disc and shaft is effectively removedeach time the valve is opened.Stockham butterfly valves are designed to operate be tweentwo flanges. If the valve installation calls for the use of onepipe flange only, a Lug style valve with Dead End Servicefeature must be used.Disc ClearancesPrior to installing the valve, it is important to make sure theID of the pipe and the pipe flanges are large enough to allow the disc edge to swing into the opening without interference.Damage to the disc edge can severly affect the performanceof the valve. Flange and pipe schedule compatibility forStockham valves is shown in Section 1 of this manual.All Stockham butterfly valves are completely bi-directional, so installation is not dependent on seat orientation. Bubble-tight shutoff will be achieved in this orientation with 25 to 150 psi ∆P across the valve.Unpacking and Storage InstructionsInstallation ToolsThe only tool required in the installation of a Stockham RSBFV is a wrench suitable for tightening the flange bolts and/or nuts required to secure the valve in-line. A hoist maybe required to help manipulate valves 10" and larger. Smaller sized valves can usually be installed by hand.

概述：
随着科学技术的进步和产品的更新，工业阀门的需求已有显著的变化。本蝶阀广泛用于电站供热系统和催化裂化主风机管道系统、钢铁、冶金、石化、电力炼油、矿山等工业管道上作切断和调节流量用。

蝶阀参数详细说明

蝶阀又叫翻板阀，是一种结构简单的调节阀，同时也可用于低压管道介质的开关控制。

蝶阀是指关闭件（阀瓣或蝶板）为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，在管道上主要起切断和节流作用。

蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。

蝶阀适用于发生炉、煤气、天然气、液化石油气、城市煤气、冷热空气、化工冶炼和发电环保等工程系统中输送各种腐蚀性、非腐蚀性流体介质的管道上，用于调节和截断介质的流动。

简介蝶阀（butterfly valve）：又称碟阀蜗轮蝶阀释义：启闭件为盘形蝶板并能绕阀体内轴线旋转的一种阀门。

结构：主要由阀体、阀杆、蝶板和密封圈组成。

阀体呈圆筒形，轴向长度短，内置蝶板。

工作原理：蝶板由阀杆带动，若转过90°，便能完成一次启闭。

改变蝶板的偏转角度，即可控制介质的流量。

常用的蝶阀有对夹式蝶阀和法兰式蝶阀两种。

对夹式蝶阀是用双头螺栓将阀门连接在两管道法兰之间，法兰式蝶阀是阀门上带有法兰，用螺栓将阀门上两端法兰连接在管道法兰上。

使用范围电动蝶阀蝶阀适用于发生炉、煤气、天然气、液化石油气、城市煤气、冷热空气、化工冶炼和发电环保、建筑给排水等工程系统中输送各种腐蚀性、非腐蚀性流体介质的管道上，用于调节和截断介质的流动。

功能用途气动蝶阀蝶阀(英文：butterfly valve)是指关闭件(阀瓣或蝶板)为圆盘，围绕阀轴旋转来达到开启与关闭的一种阀，在管道上主要起切断和节流作用。

蝶阀启闭件是一个圆盘形的蝶板，在阀体内绕其自身的轴线旋转，从而达到启闭或调节的目的。

蝶阀全开到全关通常是小于90° ，蝶阀和蝶杆本身没有自锁能力，为了蝶板的定位，要在阀杆上加装蜗轮减速器。

采用蜗轮减速器，不仅可以使蝶板具有自锁能力，使蝶板停止在任意位置上，还能改善阀门的操作性能。

工业专用蝶阀的特点能耐高温，适用压力范围也较高，阀门公称通径大，阀体采用碳钢制造，阀板的密封圈采用金属环代替橡胶环。

硬密封法兰蝶阀手册

硬密封法兰蝶阀产品概述蝶阀是随阀杆转动的圆形碟板作启闭件，实现阀门的开启或关闭，蝶阀主要作截断阀使用，也可以设计成具有调节和截断功能。

三偏心多层次蝶阀具有无机械磨损，可达零泄漏，适用于石油、化工、冶金、电力、食品、医药、给排水、气体输送等不同介质的管道上作为调节、截断流体的最佳装置。

2 启闭迅速，比较省力，启动时只需把转动90°,方便而迅速。

3结构简单，体积较小，重量较轻。

4三偏心蝶阀是指：阀杆轴线与碟板密封面偏移一定的尺寸，蝶板密封面与阀体通道轴线偏移一定尺寸，阀座回转轴线与阀体通道轴线形成一个偏心角，故称三偏心。

蝶阀从0°—90°开启时，蝶阀密封面会在开启的瞬间立即脱离阀座密封面，在其90°—0°关闭时，只有在关闭的瞬间，其蝶板圆锥形密封面才会接触并压紧阀座圆锥形密封面，所以阀座与碟板上的密封面间无任何磨擦，去除了5 扭矩密封：三偏心的结构使蝶阀关闭时，其密封主、副两密封面之间的密封比压由外加于阀杆的驱动力矩产生，不仅消除了常规弹性阀座弹性材料老化，冷流，弹性失效等因素造成的密封比压降低和消失，而且可以通过外加驱动力矩的改变，实现对其密封比压的任意调整，从而使三偏心蝶阀的密封性能改善，蝶阀的使用寿命也大大提高。
