1 Scope
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 I nlet 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.
