    Abstract - (Show below) - (Hide below)

    Specifies requirements for the material, design and performance of metal-bodied non-return valves (swing check and tilting disc types) for use in water supply and sewerage systems (swing check only) suitable for operation both in horizontal and vertical positions. Classification ranges from Class 16 to 35 valves in the size range DN 80 to DN 750 inclusive, with the maximum temperature of the medium flowing through the valve not exceeding 60 degrees Celsius.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for the material, design and performance requirements for metal-bodied flanged non-return valves (swing check and tilting disc types) for use in water supply and pressure sewerage systems (swing check only) suitable for operation in both horizontal and vertical positions.Classification includes Class 16 and 35 valves in the size range DN 80 to DN 750, inclusive, with the maximum temperature of the medium flowing through the valve not exceeding 60°C.Means for demonstrating compliance with this Standard are given in Appendix A. The products covered by this Standard include the following: (a) Non-return, free-acting valve.(b) Non-return valve with extended hinge pin suitable for position indication, micro-switches, counterweight lever arm and counterweight.(c) Non-return valve fitted with position indicator and/or counterweight lever arm and counterweight.(d) Counterweight lever and counterweight for retrofit to valve with extended hinge pins.(e) Non-return valve with resilient seated disc.NOTE: See Appendix B for purchasing requirements that should be agreed upon at time of enquiry or order.
