Pressure Reducing Valve IR-420-48
The BERMAD Model IR-420-48 Pressure Reducing Valve with Downstream Over-Pressure Guard is a hydraulically operated, diaphragm actuated control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of fluctuating demand or varying upstream pressure. The downstream over-pressure guard feature enables an immediate closing response, minimizing deviation from set point caused by a sudden drop in demand or an upstream pressure peak.
