Water Pressure Reducing Valve
with Integral By-pass Check Valve and Strainer
Page 1 of 2
Application
Ideal for use where Lead-Free* valves are required. Designed
for installation on potable water lines to reduce high inlet
pressure to a lower outlet pressure. The integral strainer
makes this device most suitable for residential and commer-
cial water systems requiring frequent cleaning because of
sediment and debris. The direct acting integral by-pass de-
sign prevents buildup of excessive system pressure caused
by thermal expansion. The balanced piston design enables
the regulator to react in a smooth and responsive manner
to changes in system flow demand, while at the same time,
providing protection from inlet pressure changes.
