Pressure Regulating Valves – SR50 Series
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.
How They WorkThe SR50 controls downstream pressure, which must always be below the inlet pressure. It is normally open until the downstream pressure (which acts on the control diaphragm) reaches the set pressure, adjustable with the spring tensioning bolt. At this point the valve closes. It opens again as soon as downstream pressure decreases slightly below the set pressure.
The large diaphragm provides for sensitive and precise control. The valve seat opens and closes until a balance is achieved between the spring force (set pressure) and the downstream pressure.
