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 ℃ for cold water application and 80 ℃ 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.
