The Bermad Model IR-420-54-bK is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to very low and stable preset downstream pressure, regardless of fluctuating demand or varying upstream pressure.

It is a Normally Closed valve, which opens in response to a remote pressure drop command and shuts in the absence of that command.
