Piston Pressure

Reducing Valve

Pressure Reducing Valves

Pressure reducing valves are devices which, when

installed in water systems, reduce and stabilize the

pressure of the water entering from the water supply

main. This pressure, in general, is too high and variable

for domestic systems to operate correctly.

The valve is constructed of lead free forged brass and

incorporatesa unique noise reducing and high flow seat

design, is easily serviced witha replaceable cartridge and

has an integral stainless steel filter, suitable for water

systems that may contain sediment and debris.
