The Bermad Model IR-430-50-R is a hydraulically operated, diaphragm actuated control valve that sustains minimum preset upstream (back) pressure, regardless of fluctuating flow or varying downstream pressure.

This valve either opens or shuts in response to remote pressure commands. When installed offline, the Bermad Model IR-430-50-R relieves line pressure in excess of preset.
