This standard BS EN 1567:1999 Building valves. Water pressure reducing valves and combination water reducing valves. Requirements and tests. is classified in these ICS categories:
23.060.40 Pressure regulators
91.140.60 Water supply systems
This European Standard specifies dimensions, materials and performance requirements (including methods of test) for Water Pressure Reducing Valves and Combination Pressure Reducing Valves, of nominal size from DN 8 to DN 100, for inlet pressures that do not exceed 1,6 MPa (16 bar) and a temperature that does not exceed 30 °C for cold water application and 80 °C for hot water application. Except when stated otherwise by the manufacturer, the valves can be mounted in any orientation.
NOTE: The use of the device specified in this standard does not override the need to use hydraulic safety devices to prevent over pressurisation.
