This European standard specifies the requirements and describes test methods for check and non-return valves. This standard is applicable to check valves installed between container valve and manifold and non-return valves installed in pilot lines except those valves, which are tested in combination with non-electrical control devices. Non-return and check valves shall allow the passage in the direction of flow and they shall prevent flow in the reverse direction.
