The Bermad Model IR-420-55-X Pressure Reducing 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 IR-420-55-X opens and shuts in response to an electric signal.

The Shuttle Valve  hydraulically connects the Solenoid  or the Pressure Reducing Pilot (PRP)  to the Valve Control Chamber . When the solenoid is closed, the PRP commands the Valve to throttle closed should Downstream Pressure [P2] rise above setting, and to open when [P2] falls below setting. Should line pressure remain below setting - the Valve opens fully. In response to an electric signal, the solenoid switches, directing line pressure through the shuttle valve into the control chamber. This causes the Valve to shut.
