IR-430-55
Pressure Relief/Sustaining Valve


The BERMAD Model IR-430-55 is a hydraulically operated, diaphragm actuated control valve that can fulfill either of two separate functions. When installed in-line, it sustains minimum preset upstream (back) pressure. When installed as a relief or circulation valve, it relieves line pressure in excess of preset. The BERMAD Model IR-430-55 either opens or shuts in response to an electric signal.
