    Abstract - (Show below) - (Hide below)

    Specifies requirements for air valves for water systems. This Standard is applicable to valves rated at 1600 kPa, 2100 kPa and 3500 kPa for sizes DN 15 to DN 400.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for metallic bodied PN 16, PN 21 and PN 35 air valves for water supply. This Standard is applicable to valve sizes DN 15 to DN 400 that are suitable for, but not limited to, use in drinking water supplies, with a maximum operating temperature of 60°C (see Note 2).This Standard covers the following types of valves:(a) Large-orifice air valve.(b) Small-orifice air valve. (c) Double-orifice air valve. (d) Anti-slam air valve.(e) Anti-vacuum valve.NOTES: 1 Purchasing guidelines are given in Appendix B.2 Based upon a maximum water temperature of 40°C within the main and the air valve being located on the top of an above-ground pipeline exposed to sunlight.
