Description

The devices covered by this standard are multi-functional products, combined integrally in a single housing or manifold to provide the required features in a compact format that is serviceable and easily installed. These devices are intended to provide the same benefits and features as the products individually manufactured and qualified under ASSE 1003-2009, Performance Requirements for Water Pressure Reducing Valves for Domestic Water Distribution Systems, and ASSE 1012-2009, Performance Requirements for Backflow Preventer with an Intermediate Atmospheric Vent, except where specific limitations have been applied to suit residential and light commercial boiler feed and applications.

Size Range

Inlet and outlet pipe sizes are ½ to ¾ NPS (15 mm to 20 mm) inclusive.

Minimum Pressure Rating

The device shall be designed and constructed for a working pressure of at least 150.0 psi (1034 kPa).

Temperature Range

The device shall be designed and constructed for normal flow temperatures of 40.0 °F to 180.0 °F (4.4 °C to 82.2 °C).

Flow Rate

Manufacturer's advertised maximum flow rate.
