    Specifies requirements for PN 16 and PN 25 metal-bodied resilient-seated gate valves for waterworks purposes.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for PN 16 and PN 25 metal-bodied resilient-seated gate valves for waterworks purposes, with a maximum operating temperature of 40°C. This Standard is applicable to the following versions: Valves of nominal sizes DN 80 to DN 750 with inside screw and non-rising spindle design, operated by a removable key, with or without a gearbox, for buried applications.Valves of nominal size DN 80 to DN 750 with inside screw and non-rising spindle design, operated by a handwheel, with or without a gearbox, for above-ground applications.Valves of nominal size DN 80 to DN 300 with outside screw and rising spindle design, operated by a handwheel, for above-ground applications where the position of the gate is required to be visible.Valves of nominal sizes DN 450 to DN 750 with an integral bypass arrangement.The design criteria of the valve and fasteners should be based on a minimum life expectancy of 50 years.Purchasing guidelines are given in Appendix B.
