    Abstract - (Show below) - (Hide below)

    This Standard specifies requirements for Class 16 and solid gate metal-bodied resilient-seated gate valves for waterworks purposes, with a maximum operating temperature of 40 degrees Celsius.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for Class 16 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(a) 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.(b) 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.(c) 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.The design criteria of the valve and fasteners should be based on a minimum life expectancy of 50 years.Means for demonstrating compliance with this Standard are given in Appendix A.NOTE: Purchasing guidelines are given in Appendix B.
