Bermad IR-430-54-KX Pressure Sustaining Valve



Bermad IR-430-54-KX Pressure Sustaining Valve
The Bermad Model IR-430-54-KX is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure and opens fully when line pressure is in excess of setting.
It is a Normally Closed valve, which opens in response to a remote pressure rise command and shuts in the absence of that command.
