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 unitized replaceable cartridge
reduces time involved with cleaning and maintenance. The direct
acting integral bypass design 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.
