Pressure Reducing Valve IR-120-54-3Q-b

The BERMAD Model IR-120-54-3Q-b is a hydraulically operated, diaphragm actuated control valve that accurately reduces higher upstream pressure to very low and stable preset downstream pressure. It is a Normally Closed valve that opens in response to a remote pressure drop command and shuts in the absence of that command. The BERMAD Model IR-120-54-3Q-b also serves as a Pressure Relief Valve protecting the system even when in closed position.
