Shanghai Kangquan Valve Co., Ltd.

Pressure Relief Valve

Description

The valves maintain a preset downstream pressure, regardless of upstream pressure or flow fluctuation. The main valve is controlled by a pilot valve, which makes the main valves modulating to maintain the downstream pressure.

The pressure relief valve is an intelligent valve that uses the self energy of the medium to regulate and control the pressure in pipes. The valve can be used in domestic water supply, fire fighting water supply and other industrial water supply systems. The outlet pressure of the main valves can be regulated through the adjustment of the pressure reducing valves; the outlet pressure does not vary along with the inlet pressure and inlet flow. Accordingly, the outlet pressure can be safely and reliably maintained at a preset value and the preset value can be adjusted according to actual needs to obtain your pressure reducing goal. This valves is precise in pressure reduction, stable in performance, safe, reliable, easy, convenient to install and adjust and offers a long service life.
