Safety Pressure Reducing Valve 22mm For Protect Pump With Flange End BS5163

Ductile Iron GGG50 Y Type  Pump Hydraulic Control Valve For Protect Pump , Flange End

Diaphragm type multifunctional pump control valves is installed at the outlet of pump in high building

water supplying system and other to prevent backward flow,water-hammering,water-hitting.

The valves have the function of the following valves: motorized valves,non return valves and

water-hammering eliminator and can improve the safety in the system.The valves have slow-open,

quick-close and slow-close function to prevent water-hammering when open or close pump.

Only push the button for closing or opening pump and the valves can run according to the pump's operation procedure with large flow and little pressure loss.JD745X diaphragm type multifunctional

pump control valves is for DN 600 or less valves.

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.
