Description

These devices shall consist of two independently acting check valves biased to a normally closed position. An atmospheric port shall be located between the check valves and shall be biased to a normally open position. The port shall vent liquids, gases, or both, under backflow conditions.

Minimum Flow

The device shall meet the minimum flow capacity as described in Table 1.

Type indicates the flow capacity of the device and not the connection size of the device.

Inlet and Outlet Connections

Inlet and outlet connections shall include 1/4" (8 DN), 3/8" (10 DN), and 1/2" (15 DN) nominal pipe size.

Pressure Range

These devices shall function properly over the pressure range of 10.0 psi to 200.0 psi (68.9 kPa to 1379 kPa).

Temperature Range

These devices shall function properly over the temperature range of 40.0 °F to 130.0 °F (4.4 °C to 54.44 °C).
