Ductile Iron GGG50 Flange End Pump Hydraulic Control Valve For Protect Pump
Pump Control Valve eliminates damaging water surges (hammer) caused when pump starts up and
shuts off. The electrically activated valves gradually opens when pump starts up, and slowly closes
before the pump is switched off. The valve also operates as a slow control check valves, preventing
reverse flow and water hammer when power failure.

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.
