Selection or installation of equipment should always be accompanied by competent technical assistance. You are encouraged to contact Armstrong International, Inc. or its local representative for additional information.Bulletin No. AY-764-DInstallation Instructions1. An Armstrong Inverted Bucket Steam Trap isrecommended to drain condensate at the inlet of the Pressure Reducing Valve (PRV). A Liquid Drainer is recommended for air service.2. An Armstrong Y-Strainer (20-100 mesh, dependingon system dirt) should be installed before the PRV to reduce the chance of dirt fouling.3. Pressure gauges should be installed before and afterthe PRV.4. If system cannot be turned off to service PRV thenpiping a by-pass line with a high quality globe valve around the PRV will allow manual system operation while the PRV is being serviced.5. Do not install quick opening or closing valvesdownstream of the PRV.6. Install the PRV with the fl ow in the direction of thearrow on the body.Installation for Steam ServiceInstallation for Air ServiceGD-30Note:Safety Relief Valve to be set at10 psi higher or 10% higher thanthe downstream pressure, whicheveris greater.Safety ReliefValveGateValveBy-PassArmstrongTVS TrapArmstrongStrainerGateValveGlobeValve2Troubleshooting Guide1. Close the gate valves before and after the pressurereducing valve. Open the globe valve slowly in the bypass line and blow down the inlet piping. Adjust the opening of the bypass valve so the safety valve does not blow. After blowing the system down, close the bypass valve.2. Slowly open the inlet side gate valve to the fully openposition, and partially open the outlet valve so only a small amount of steam or air can pass.Start-Up and Adjustment ProceduresImproper adjustment of the pressure reducing valve may cause hunting, scale problems, water hammer, etc., and damage to the valve itself. Damaged pressure gauges, leakage or opening of a bypass valve, or clogging of an inlet strainer may cause problems similar to that of a malfunctioning reducing valve.Adjust the valve as follows:3. To increase the downstream pressure, place yourhand on the top of the adjusting handle and pull vertically up. When in the fully up position turn the handle clockwise until the desired pressure is obtained on the downstream pressure gauge.4. Release the handle and it will automatically retractwhich will lock the adjusting handle in place.5. Slowly open the outlet valve to the fully open position.ProblemCausesSolutionsThe desired pressure cannot be obtained.The inlet pressure is too low or high.Change the pressure to the appropriate level.The sensing port of the outlet pressure is clogged with foreign matter.Disassemble and clean the sensing port.The valve size is smaller than what is required.Change the valve size to the appropriate one.The adjustment is not appropriate.Readjust according to the adjustment procedure. (See start-up procedure)The inlet strainer is clogged by foreign substance.Disassemble and clean the strainer.The pressure gauge is not functioning properly.Replace the pressure gauge.The outlet pressure rises higher than the specified pressure.The valve or valve seat is contaminated by foreign substance.Disassemble and clean the valve or the seat.The by-pass valve is leaking.Repair or replace the by-pass valve.Abnormal noise is heard.The reducing ratio is excessively large.Reduce pressure by staging with second PRV.Water hammer (for steam service).Install a steam trap at the reducing valve inlet.There is a fast closing valve near the PRV.Provide as long a distance as possible between the two valves.3GD-30 1/2” - 1”Disassembly1. Eliminate pressure from inside the valve. Make sure the valve is completely free from pressure.2. Pull up and turn the handle (4) in the direction (counterclockwise) as shown on the nameplate of the handle to make the spring (12) free (not loaded).3. Remove the bolts (15) and take away the spring housing (2) (the handle cannot be disassembled).Take out the spring (12), bellows (10) and valve rod (8).4.

When you want to use it, you can turn the adjusting screw clockwise; this can compress the adjusting spring, move the diaphragm down and then open the secondary valve disc, the medium also enters above the main valve seat through “a”hole to “b”hole, make the main valve disc open and then enters under the diaphragm through “c” hole. But when the downstream pressure is exceed the set pressure, the medium moves the diaphragm up and compresses adjustingspring, and then the secondary valve disc closes slowly, because the flow reduces, the downstream pressure get a new balance, on the other hand, when the downstream pressure is less than the set pressure, the gap between the main valve disc and the main valve seat increases and then the flow increases too and then make the downstream pressure get a new balance.Installation and maintenance:1.Clean the valve and the pipe line and remove the dirt beforeinstallation, at the same time the valve must be installed in horizontal direction, bracket is needed when the valve deadweight is heavy or vibration exists at the site.2.While installing, make sure the flow direction and thedirection marked on valve body is consistent, and a bypass pipe is usually required. When the valve size and the pipe size differ, reducer should be adopted. The installing site should have sufficient space for a convenient usage and maintenance.3.When the valve is put into use, the bypass globe valve mustbe opened, remove the condensate and the water vapor mixture in order to avoid the water hammer occurred by opening the valve. If there is no unusual phenomenonappears, you can turn the adjusting screw clockwise till getting the outlet pressure we need, then lock the nut and cover the top cap.4.A filter must be installed before the pressure reducing valvewhich prevents the impurities from getting into the valve. 5.There must be a straight pipe at least 600mm and 1000mmseperately before and after the pressure reducing valve.6.A water-vapor separator and a steam trap should be installedbefore the pressure reducing valve, atfter which a steam trap should also be installed.7.Pressure reducing valve should be kept in a dry room, both ofwhich should be blocked with blind plates. Do not keep in piles.8.If the pressure reducing valve will be kept for a long time, wemust check it regularly, clean up the dirt and spread some rust-proof oil on the movement part and the machined surface.9.If the outlet pressure is higher than the inlet pressure, wemust reset the pressure reducing valve as follows:①Shut off the upstream isolating valve;②Relief the downstream pressure;③Turn the adjusting screw counterclockwise, make it in a freepoisition.④ Open the upstream isolating valve slowly till full open. ⑤ Turn the adjusting screw clockwise, the outlet pressure rises slowly to the set value, then lock the adjusting screw. ⑥ If you adjust the pressure too high, you must readjust it from step 1 to step 5 (adjust from low pressure to high pressure only) Installation diagram:12 3 4 5 6 filter pressure gauge Pressurereducing valveGlobe valveSafety valveBypass pipe。

使用说明书减压阀宏源自动化仪表有限公司概述减压阀（Reducing valve）是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后的生活生产器具。

按结构形式可分为膜片式、弹簧薄膜式、活塞式、杠杆式和波纹管式；按阀座数目可人为单座式和双座式；按阀瓣的位置不同可分为正作用式和反作用式。

第一章 产品技术参数一、工作原理蒸汽减压阀是采用控制阀体内的启闭件的开度来调节介质的流量，将介质的压力降低，同时借助阀后压力的作用调节启闭件的开度，使阀后压力保持在一定范围内，在进口压力不断变化的情况下，保持出口压力在设定的范围内，保护其后的生活生产器具。

本类阀门在管道中一般应当水平安装。

蒸汽减压阀是气动调节阀的一个必备配件，主要作用是将气源的压力减压并稳定到一个定值，以便于调节阀能够获得稳定的气源动力用于调节控制。

蒸汽减压阀的工作由阀后压力进行控制。

当压力感应器检测到阀门压力指示升高时，减压阀阀门开度减小；当检测到减压阀后压力减小，减压阀阀门开度增大，以满足控制要求。

蒸汽减压阀—该阀门的减压比必须在一定程度上高于系统值；即使在最大或者最小流量时它也应该能够对正作用或者反作用控制信号做出响应。

这些阀门应该针对有用控制范围选择，即最大流量的20%到80%。

正常为等比型或者具有等比特性。

活塞式减压阀工作原理：减压阀出厂时，调节弹簧处于未压缩状态，此时主阀瓣和副阀瓣处于关闭状态，使用时按顺时针方向转动调节螺钉，压缩调节弹簧，使膜片下移顶开副阀瓣，介质由a孔通过副阀座到b孔进入活塞上方，活塞在介质压力作用下，向下移动推动主阀瓣离开主阀座，使介质流向阀后，同时由c孔进入膜片下方，当阀后压力超过调定压力时，推动膜片上移压缩调节弹簧。

副阀瓣随之向关闭方向移动，使流入活塞上方的介质减小，压力也随之下降，此时主阀瓣在主阀瓣弹簧力的推动下上移，使主阀瓣与主阀座的间隙减小，介质流量随之减少，使阀后压力随之下降到的新的平衡，反之当阀后压力低于调定压力时，主阀瓣和主阀座间隙增大，介质流量随之增加，使阀后压力随之增高达到新的平衡。
