Devices shall be permitted to be with or without an integral by-pass relief valve.

Size Range

Connection pipe sizes shall be ½ NPS, ¾ NPS, 1 NPS, 1¼ NPS, 1½ NPS, 2 NPS, 2½ NPS and 3 NPS (12.7 mm, 19.1 mm, 25.4 mm, 31.8 mm, 38.1 mm, 50.8 mm, 63.5 mm and 76.2 mm).

Minimum Working Pressure

Devices shall be designed for a minimum working pressure of 250.0 psi (1723.8 kPa).

Temperature Range

The devices shall be designed for temperatures of 33.0 °F (0.6 °C) to 140.0 °F (60.0 °C) minimum.
