Description

These assemblies consist of 2 independently acting check valves, internally force loaded to a normally closed position and separated by an intermediate chamber (or zone) in which there is a hydraulically operated relief means for venting to the atmosphere, internally force loaded to a normally open position. These assemblies are designed to operate under continuous pressure conditions. The assembly shall include 2 properly located, tightly closing shut-off valves per Section 1.3.2.8; and properly located test cocks per Section 1.3.2.6.

Pressure Rating

The maximum working pressure shall be at least 175 psi (1206.6 kPa).

Temperature Range

Assemblies for cold water applications shall be designed for a minimum temperature range of 33.0°F to 140.0°F (0.6°C to 60.0°C).

Assemblies for hot water applications shall be designed for a minimum temperature range of 33.0°F to 180.0°F (0.6°C to 82.2°C).
