CENTURY INSTRUMENT隔膜阀730-RV系列介绍
730-RV型隔膜控制阀
用于减压服务，背压控制或压力释放应用处理去离子水，浆液，腐蚀性或研磨性液体，或任何需要隔膜式阀门的服务。
该组件包括一个630号气动隔膜阀，可根据需要常开或常闭，60-P压力先导阀和可选的1725号化学附件，阀门定位器和单或双限位开关。
对于背压控制或压力释放服务，压力传感线从主阀上游的点连接到压力导向器上的化学附件。
对于减压服务，压力传感线必须位于主阀下游的一点。
特征
常开（弹簧打开）和常闭（弹簧关闭）均可带或不带阀门定位器和限位开关。定位器建议用于遇到流量和/或压力波动较大的安装，特别是在减压应用中。
当阀门用于浆液和腐蚀性或磨蚀性液体以隔离60-P压力先导阀中的压力测量元件时，提供化学附件。
对于需要密切调节控制的应用，压力先导阀配有可调节的比例机构。
由于No.60-P气动先导阀的机构，所有730系列控制阀必须安装在直立位置。
Model 730-RV Diaphragm Control Valve
For pressure reducing service, back pressure control or pressure relief on application handling de-ionized water, slurries, corrosive or abrasive liquids, or any service which requires a diaphragm type valve.
The assembly consists of a No. 630 air-operated diaphragm valve either normally open or normally closed as desired, a No. 60-P pressure pilot and optional No. 1725 chemical attachment, valve positioner and single or dual limit switches.
For back pressure control or pressure relief service a pressure sensing line is connected to the chemical attachment on the pressure pilot from a point upstream from the main valve.
For pressure reducing service the pressure sensing line must be from a point downstream from the main valve.
Features
Both normally open (spring open) and normally closed (spring closed) are available with or without valve positioner and limit switches. Positioners are recommended for installations where large fluctuations in flow and/or pressure are encountered, particularly on pressure reducing applications.
The chemical attachment is furnished when the valve is to be used on slurries and corrosive or abrasive liquids to isolate the pressure measuring element in the 60-P pressure pilot.
For applications where close modulating control is required, the pressure pilot is provided with an adjustable proportioning mechanism.
Because of the mechanism in the No. 60-P pneumatic pressure pilot, all Series 730 control valves must be installed in an upright position.
