MISCELLANEOUS
WATER PRESSURE
REDUCING VALVE
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

BREAKER ASSEMBLY
Designed for installation on indoor and
outdoor point of use applications to protect
against backsiphonage of contaminated water
into the water supply. During start-up and
operation a separate diaphragm seals the air
inlet from the water supply preventing spillage.
The assembly is designed for use under
constant pressure and provides protection
where a potential health hazard exists.

Series 007 Double Check Valve Assemblies
prevent the backflow of contaminated water
into the potable water supply. It consists of a
bronze 2 in body construction that is easy to
maintain and service. Series 007 is ideal at
referenced cross-connections identified as
non-health hazard applications. Check with
local inspection authorities for installation
requirements. Maximum Working Pressure:
