Pressure Reducing Valve

The BERMAD Model IR-120-55-3Q-X is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower and stable preset downstream pressure. It either opens or shuts in response to an electric signal. The Bermad IR-120-55-3Q-X also serves as a Pressure Relief Valve, protecting the system even when in closed position.
