Air-Release, Air/Vacuum, and Combination Air Valves for Water and Wastewater Service
N C512
Annotation
This standard describes ?-in. (13-mm) through 6-in. (150-mm) air-release valves and ?-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.

Воздушный выпуск, Воздух/Вакуум и Воздушные Клапаны Комбинации для услуги Воды и Сточных вод
Этот стандарт описывает -in. (13 мм) до 6 - в. (150-миллиметровые) клапаны воздушного выпуска и -in. (13 мм) до 20 - в. (500-миллиметровые) клапаны воздуха/вакуума и воздушные клапаны комбинации, имеющие серый чугун, податливое железо, углеродистую сталь, или организации нержавеющей стали и покрытия. Клапаны разработаны для использования в системах воды или сточных вод с максимальными давлениями дизайна 300 фунтов на квадратный дюйм (2,070 кПа [прибор]), жидкие температуры в пределах от вышеупомянутого замораживания к максимуму 125°F (52°C), и жидкий pH, больше, чем 6 и меньше чем 12.
