Fixed firefighting systems. Components for gas extinguishing systems - Requirements and test methods for check valves and non-return valves Ingestion-build-68772 Cadmium: 0This European Standard specifies the requirements and describes test methods for check and non return valves for CO2, inert gas or halocarbon gas fire extinguishing systems. Non return and check valves allow the passage in the direction of flow and they prevent flow in the reverse direction. This European Standard is applicable to check valves installed between container valve and manifold and non return valves installed in pilot lines, except those
