Product Description
The BERMAD Pressure Reducing Control Valve with Solenoid 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. The BERMAD Model 220-55-X 3W either opens or shuts in response to an electric signal.

Technical Data
Operation
The Shuttle Valve 1 hydraulically connects the Solenoid 2 or the Pressure Reducing Pilot (PRP) 3 to the Valve Control Chamber 4. When the solenoid is closed, the PRP commands the Valve to throttle closed should Downstream Pressure P2 rise above the setting and to open fully when P2 is below the setting. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber, shutting the Valve. The solenoid also features local manual closing.
