scope:
This standard describes ½-in. (13-mm) through 6-in. (150-mm) air-release valves and ½-in. (13-mm) through 20-in. (500-mm) air/vacuum valves and combination air valves having gray cast-iron, ductile-iron, carbon steel, or stainless-steel bodies and covers. The valves are designed for use in water or wastewater systems with maximum design pressures of 300 psig (2,070 kPa [gauge]), liquid temperatures ranging from above freezing to a maximum of 125°F (52°C), and a liquid pH greater than 6 and less than 12.
Purpose
The purpose of this standard is to provide the minimum requirements for air-release valves, air/vacuum valves, and combination air valves for water and wastewater service, including material, design, testing, inspection, marking, and packaging for shipment.
