However, due to installation safety, the definition of an equal allocation for all valves is recommended.!The following mandatory allocation is to be selected when the room temperature controller CRK24-B1 from Belimo is used, due to the control characteristics:Sequence 1 = cooling Sequence 2 = heatingDirection of flowThe direction of flow must be observed.Sequence 1Sequence 2100%Marking of the connection gatesThese are numbered from 1 to 6 for the purpose of secure allocation of the connections during planning and installation.Motorisation6-way characterised control valves are motorised with a rotary actuator. The control must be modulating.R3015-..-..-B1R30..-..-..-B2/B34 / 86-way characterised control valve • en • 09.2020 • Subject to changes 6-way characterised control valvesDesign and dimensioningControl characteristicsTo ensure a valve attains good control characteristics thus a long service life for the control element, it needs to be correctly designed with the correct valve authority.The valve authority av is the benchmark for the control characteristics of the valve in combination with the hydraulic network. The valve authority is the relation between the differential pressure of the fully open valve at nominal flow and the maximum differential pressure for the closed valve. The higher the valve authority, the better the control characteristics. The smaller the valve authority av becomes, the more the operational behaviour of the valve will deviate from the linearity i.e.. the poorer the volumetric flow control will be. In practice the intended av is >0.5.Design when using glycolTo reduce the freezing point of water, salt was added to the water in the past. These werecalled brine applications. Today glycol is used and we talk about cold agents. Depending on the concentration of the cold agent used (type of glycol) and the medium temperature, the density of the water/glycol mixture varies between 1 and 9 percent. The resultant volume deviation is less than the permissible volume tolerance of the valve's k vs value (by ±10 percent according to VDE 2178) and as a rule need not be taken into account even if glycol requires a slightly higher k v value.Depending on the type of glycol, compatibility with the valve materials used must be guaranteed and the permissible maximum concentration (50 percent) must not be exceeded.k vs valuesSince different k vs values are often required for heating and cooling, 6-way characterised control valves are available with different k vs values for sequences 1 and 2. For a full overview, see data sheet R30..-..-..-B.. .Using an additional flow limiterWhen using additional flow limiting valves (e.g. PIQCV C2..QP(T)-.. with manual flow rate setting) or an additional pressure-independent control valve (e.g. motorised PIQCV) atthe system level, it is not necessary to use the flow characterised disc in the 6-way valve in the system to reduce the k vs value. The differential pressure required for operation is kept as low as possible in this manner. In addition, possible noise generation in conjunction with the additional components used is avoided.DN15 max. k vs 0.63 m 3/h: DN15 max. k vs 1.8 m 3/h: DN20 max. k vs 4 m 3/h: DN25 max. k vs 6.3 m 3/h:R3015-P63-P63-B1 R3015-1P8-1P8-B2 R3020-4-4-B2 R3025-6P3-6P3-B3Switching between sequencesAs with all combined heating/cooling elements in 4-pipe systems, mass displacement can occur when using 6-way characterised control valves.Mass displacementWith each switch (from cooling to heating operation or from heating to cooling operation) water is displaced from one circuit to the other. Due to the different medium temperatures, the density of this water differs. Due to the constant volume in the heating/cooling element, the quantity of water displaced has a different mass. When switching from cooling to heating, more mass is shifted then when switching from heating to cooling. This mass displacement can lead to the cooling circuit being emptied.It is important to cater for this normal behaviour. For corresponding recommendations, see the chapter 'Hydraulic circuits'.MediaDue to the mass displacement that occurs, the medium in both circuits needs to have the same properties (glycol concentration). 6-way characterised control valve • en • 09.2020 • Subject to changes 5 / 86-way characterised control valvesProtection of the heating/cooling element (pressure release function)In cases of combined heating/cooling elements, the medium is enclosed in the element when they are in closed status (no heating or cooling). The pressure of the enclosed medium can rise or fall due to changes in medium temperature caused by the ambient temperature. The 6-way characterised control valve have an integrated pressure release function for the purpose of compensating for such pressure changes.Design for pressure releaseThe upper ball of the characterised control valve has a groove that forms a link between the 'Supply Sequence 1' (Gate 1) connection point and the heating/cooling element connected at Gate 2 when the valve is closed.Pressure release Groove for pressure releaseFunction means of the connection to the 'Sequence 1' circuit. No further flow of water takes place after the pressure compensation due to the same absolute pressures in Sequence 1, in the heating and cooling element and in the lower closing element, which closes air-bubble tight.Behaviour in hot or cold operationThe pressure relief function has no influence on the hot or cold operation. When operating sequence 1, the function is on the same side as the desired water flow. When operatingsequence 2, the pressure relief function is not active. A direct mixing of water of the sequences of 1 and 2 is not possible duration operation.k αControl sequence 1Position Valve closedControl sequence 21) Positioning signal for closed position:Operating range drive 2…10 V: Y = 6 Volt Operating range drive 0.5…10 V: Y = 5.25 VoltValve leakage rateEach water circuit is channeled through two valve cones (series circuit). As a result of the continued air-bubble tight closing of the lower closing element 2, the valve continues to exhibit Leakage rate A in accordance with EN 12266-1, even for Sequence 1.Equivalent circuit diagramPressure release6 / 86-way characterised control valve • en • 09.2020 • Subject to changes 6-way characterised control valvesHydraulic circuitsFor correct operation, the following planning instructions need to be complied with, among others:MediaThe medium in both circuits needs to have the same quality (glycol concentration).System pressureThe system pressures in the heating and cooling circuit must have the same value.Possible hydraulic circuitsIn a 4-pipe system with heating and cooling circuits, the effect of mass displacement always exists regardless of the valve used (see chapter on mass displacement). To cater for this behaviour and prevent mass displacement, there are various solutions and corresponding precautionary measures.1. Two expansion vessels– 2. One expansion vessel– One expansion vessel for both circuits. Connection point on the suction side of the pumps.– Pumps at the same height.– Connection line between heating circuit return and cooling circuit return.– The same static pressure on the suction side of the pumps.3. Two expansion vessels in a hydraulic coupling system– The same static pressure on the suction side of the pumps.– Pumps at the same height.– The 2-way valve remains closed during operation.– The 2-way valve will open if the pressures p Heating and p Cooling exhibit a certain difference due to the mass displacement.– The system pressures are balanced.– The 2-way valve is closed again after the compensation.6-way characterised control valve • en • 09.2020 • Subject to changes 7 / 86-way characterised control valvesInstallation/Commissioning/Pressure testing/MaintenanceValve positionThe ball position can be discerned by means of the marking on the top of the spindle.Valve delivery conditionThe valves are delivered ex works as shown with the picture below.Delivery condition conforms to valve position 90°/positioning signal 10 V.Delivery with valve installedFor visualisation purposes, the actuator has two green dots.Only valid for R30..-..-..-B2/B3R3015-..-..-B1 cannot be supplied with the actuator installed ex worksPressure testing Due to the built-in pressure release safety function, the following needs to be observed:Pressure testing with connected heating/cooling elementIf the connected consumer circuit is also to be tested, pressure testing can be performed without additional restrictions in valve positions 'Sequence 1 open' (angle of rotation 0°) or 'Sequence 2 open' (angle of rotation 90°).When tested in closed valve position (45°), note that the connected heating/cooling element is likewise pressurised with the pressure in sequence 1.Pressure testing without connected heating/cooling elementIn valve closed position (45°) the sequence 1 test medium flows via gates 1 and 2. Thisbehaviour does not constitute a malfunction since the valve closes both water circuits reliably due to the air-bubble tightness of the second closing element during operation.Possibilities:– Individual testing of water circuits1. Sequence 1 test with valve in 90° positionNote: Prior to switching, sequence 1 needs to be emptied. 2. Sequence 2 test with valve in 0° positionor– Additional isolation of gate 2Maintenance 6-way characterised control valves are maintenance-free.R3015-..-..-B1R30..-..-..-B2/B3All inclusive.Belimo worldwide: SwitzerlandBELIMO Automation AG Swiss SalesBrunnenbachstrasse 1CH-8340 HinwilTel. +41 (0)43 843 62 12Fax +41 (0)43 843 62 66****************www.belimo.ch。

普通的溢流阀就是开启和关闭两个位置，比例阀在开启溢流时可以有多个位置。

1：以输入电流线性控制压力和流量，达到最优功率配置。

为执行元件提供必须的最小压力和流量。

2：可根据负载压力，以压差保持最小值控制泵的压力，是一种低能耗的调速阀。

3：此阀具有温度补偿功能，能使所控制流量稳定而不受油液温度的影响。

1:安装位置：正确的安装位置是使放气孔朝上以便试车时排出油路中空气。

若遇到阀必须垂直安装时，订货时请特别说明。

2:空气排除：将圆后盖朝上的放气孔螺丝打开（请将系统压力调在30bar）让空气排出，当阀内充满油不再见气泡后，将螺丝再锁紧。

3:手动调压螺丝：当电气控制发生故障时，而临时需要压力供应，此刻可将手动调整螺丝顺时针旋入即可；平时则复归原位。

4:回油管路：回油背压尽量低，油管末端直接插入油面之下。

避免管路曲折或有限流现象。

5:最高安全压力设定：依实际油泵流量及实际使用压力而决定，通常在油泵流量100/min以下时，追加15bar即可。

A概述阀对流量的控制可以分为两种：一种是开关控制：要么全开、要么全关，流量要么最大、要么最小，没有中间状态，如普通的电磁直通阀、电磁换向阀、电液换向阀。

This gap can be increased or de -creased by turning the adjusting screw with internal hex.The piloted non-return function can be used for a temporary intermediate stop. If a control signal is applied, the exhaust air flow control takes effect. If no control signal is applied, the valve shuts off the exhaust air from the drive and the drive stops temporarily.By actuating the integrated manual ex -haust function, it is possible to manu -ally exhaust the pneumatic drive.G1/41)More information /x/topic/crc52023/08 – Subject to change d I nternet: /catalogue/...One-way flow control valves VFOF, function combinationDatasheetMaterialsSectional view Standard nominal flow rate qnN in flow control direction at 6 > 5 bar as a function of turns of the adjusting screw n Standard flow rate qn in flow control direction at 6 > 0 baras a function of turns of the adjusting screw n VFOF-LE-BAH/VBNF-LBA nq n N [l /m i n ]12345678910100200300400500600VFOF-LE-BAH/VBNF-LBAnq N [l /m i n ]12345678910100200300400500600700800900VFOF-…-G18-Q6VFOF-…-G14-Q8Flow rate value tolerance: ±20%VFOF-…-G18-Q6VFOF-…-G14-Q8Flow rate value tolerance: ±20%Minimum pilot pressure p21 as a function of operating pressure p1VFOF-LE-BAH/VBNF-LBAp1[bar]p 21[b a r ]123456789100123456451One-way flow control valves VFOF, function combinationDatasheet1)Unactuated6d I nternet: /catalogue/...Subject to change – 2023/08Festo - Your Partner in AutomationConnect with us/socialmedia 1Festo Inc.2Festo Pneumatic 3Festo Corporation 4Regional Service Center 5300 Explorer DriveMississauga, ON L4W 5G4CanadaAv.

进、回油节流调速回路的不同之处：
回油节流调速回路回油腔有一定背压，故液压缸能承受负值负载，且运动速度比较平稳。
进油节流调速回路容易实现压力控制。工作部件运动碰到死挡铁后，液压缸进油腔压力上升至溢流阀调定压力，压力继电器发出信号，可控制下一步动作。
