    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for metallic-bodied PN 10, PN 16 and PN 21 air valves for sewerage. This Standard is applicable to valve sizes DN 50 to DN 200 suitable for wastewater, 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 valveNOTES:1. Purchasing guidelines are given in Appendix B.2. Based upon a maximum sewage temperature of 40°C within the main and the air valve being located on the top of an above-ground pipeline.
