Differential pressure control valve S800X

Differential pressure control valve S800X

The SHUOTE Model S800x Differential Pressure Relief valve is a hydraulically operated, pilot-controlled , modulating vaIve. It is designed to maintain a constant pressure differential between any two pressure points in a system where the closing of the vaIve directIy Causes the differential pressure to increase. The differential pressure control valve tends to open on an increase in differential pressure and close on a decrease in differential pressure.

In operation the valve is actuated by line pressure through a pilot control system sensing from two points across which a differential is to be maintained. operation is completely automatic and pressure settings may be easily changed.
