Bermad IR-430-55-R Pressure Relief/Sustaining Valve



Bermad IR-430-55-R Pressure Relief/Sustaining Valve

The Bermad Pressure Relief/Sustaining Valve with Solenoid Control is a hydraulically operated, diaphragm actuated control valve. This valve sustains minimum preset upstream (back) pressure regardless of fluctuating flow or varying downstream pressure. It either opens or shuts in response to an electric signal. When installed offline, the Bermad Model IR-430-55-R relieves line pressure in excess of preset pressure.
