Piston Pressure Reducing Valve (PN16)
Pressure reducing valve is a special device to auto-matically
reduce the working pressure of pipeline, which can reduce
the higher water pressure of the pipeline before the valve
to the level required by the pipeline after the valve.
It is widely used in high-rise buildings, areas with high
water pressure in urban water supply network and other
occasions to ensure that each water point in the water
supply system gets proper service water pressure and flow.

Piston Pressure Reducing Valve (PN25)
In residential water supply system, the pressure of tap
water network is usually high and unsta-ble, the pressure
reducing valve is used in this water supply system to reduce
and stabilize the pressure of tap water in households.
Reliable quality pressure reducing valves not only ensure
stable downstream pressure but also have the function of
pressure resistance and anti-scaling.
