Bermad IR-220-54-3W-X Pressure Reducing Valve with Hydraulic Relay



Pressure Reducing Valve with Hydraulic Relay IR-220-54-3W-X

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

The 3-Way Hydraulic Relay Valve (3W-HRV) 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. The 3W-HRV switches upon pressure drop command, directing line pressure into the control chamber, and thereby causing the main Valve to shut. The 3W-HRV also features local manual closing.
