Building valves. Water pressure reducing valves and combination water reducing valves. Requirements and tests. Ingestion-build-109673 BS EN ISO 97121 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
