SR50 Series Pressure Regulating (Reducing) Valves

The Chemline SR 50 Series Pressure Regulating (Reducing) Valves maintains a set downstream pressure independent of higher variable upstream pressures. As downstream pressure increases reaching the set pressure, the valve closes. It opens as soon as the downstream pressure decreases below set pressure. The SR 50 is sensitive and provides precise control. One application is to protect filters from damaging pressure surges.
