    Abstract - (Show below) - (Hide below)

    Specifies requirements for Class 10 flanged, wafer and lugged, rising and non-rising spindle, uni-directional and bi-directional, gland box and bonneted knife-gate valves of sizes DN 50 to DN 1500 inclusive for cold potable water supply (up to 40 degrees Celsius) and drainage and sewerage systems continuous flow up to 45 degrees Celsius.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for Class 10 flanged, wafer and lugged, rising and non-rising spindle, uni-directional and bi-directional, gland box and bonneted knife-gate valves of sizes DN 50 to DN 1500 inclusive for: (a) cold potable water supply (up to 40°C);(b) drainage and sewerage systems (continuous flow up to 45°Cittent flow up to 95°C). The valves are designed for operation by manual hand wheel either above ground or buried or submerged with an extension spindle. Means for demonstrating compliance with this Standard are given in Appendix A. NOTES: 1 Purchasing guidelines are given in Appendix B. 2 The design of the extension spindle is not covered in this Standard.
