Hydraulic Pressure Reducing Valves DN15 ~ DN450 / Pressure Relief Valve

Ductile Iron GGG50 Diaphragm Hydraulic Pressure Reducing / Relief / Sustaining Valve

The valve instantly opens when the pressure in the pipeline exceeds the preset safe level, thus relieving excessive pressure from the pipeline. When the pressure returns to normal, the valve closes slowly, at an adjustable speed. The valves also can be used to sustain upstream pressure to a preset pressure value.

Typical Installation Diagram

Main Technical Feature

The valves maintains a preset downstream pressure, regardless of upstream pressure or flow fluctuation.

The main valves is controlled by a pilot valves, which makes the main valves modulating to maintain

the downstream pressure.

The 200X pressure reducing valves is an intelligent valves that uses the self energy of the medium to

regulate and control the pressure in pipes.

The 200X pressure reducing valves 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.
