PRODUCT INFORMATION

Bermad IR-472-55-bKU Flow Control and Pressure Reducing Valve

The Bermad Model IR-472-55-bKU is a hydraulically operated, diaphragm actuated control valve that limits demand and reduces downstream pressure to constant preset maximum values. It either opens or shuts in response to an electric signal.

TECHINCAL DATA

OPERATION

Shuttle Valve (SV-1) hydraulically connects the Flow Pilot (FP) or the Pressure Reducing Pilot (PRP) to the Valve Control Chamber, through Shuttle Valve (SV-5). Pressure Differential across the Orifice Assembly is in direct proportion to demand. The FP, continuously sensing, commands the Valve to throttle closed should demand rise above setting. The PRP commands the AMV to reduce Downstream Pressure to pilot setting. In response to an electric signal, the Solenoid switches and pressurizes SV-5, which thereby directs line pressure into the control chamber, shutting the Valve.
