Description
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; alternatively, 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.
