Material, design and performance requirements for copper alloy globe and diaphragm valves for wet rising mains to BS 5306-1. Covers high and low pressure types.

This Part of BS 5041 specifies requirements for copper alloy globe valves generally complying with BS 5154 and diaphragm valves generally complying with BS 5156, both suitable for installation as landing valves on wet risers. The valves have screwed or flanged inlets and also delivery hose connections complying with BS 336. This standard covers valves of nominal pressure (PN) designations 15 bar and 20 bar and nominal inlet sizes DN 40 to DN 65 for flanged ends and 1½ and 2½ for screwed ends.

NOTE 1 Unless otherwise stated all pressures are gauge pressures expressed in bar: 1 bar = 105 N/m2 = 100 kPa.

NOTE 2 Information which the purchaser is recommended to supply to the manufacturer is given in Appendix B and does not form part of the specification.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
