Bermad IR-420-50-RXZ Pressure Reducing Valve



Pressure Reducing Valve IR-420-50-RXZ

The BERMAD Pressure Reducing Valve with Hydraulic Control is a hydraulically operated, diaphragm actuated control valve. It reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand and opens fully upon line pressure drop. This valve either opens or shuts in response to a remote pressure command.

The Shuttle Valve hydraulically connects the Pressure Reducing Pilot (PRP) to the Valve Control Chamber. The PRP commands the Valve to throttle closed should Downstream Pressure rise above pilot setting and to open fully when it drops below pilot setting. Upon pressure rise command, the shuttle valve automatically switches, allowing pressurization of the control chamber, which causes the main Valve to shut. The Manual Selector enables local manual closing.
