2" DOUBLE CHECK VALVE ASSEMBLY

PRESSURE VACUUM BREAKER ASSEMBLY

WATER PRESSURE REDUCING VALVE

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: 175psi Locke# M1276 0062427 2" Double Check Valve Assembly

Designed for installation on potable water lines to protect against backsiphonage of contaminated water into the potable water supply. Assembly shall provide protection where a potential health hazard exists.

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 Locke# M1692 70 ½" Water Pressure Reducing Valve M1693 70 ¾" Water Pressure Reducing Valve M1694 70 1" Water Pressure Reducing Valve
