How are swing check valves installed?

Check the swing check valve for damage before installation. Ensure the valve moves smoothly. Damaged parts may not be fitted. Ensure that only swing check valves are fitted, whose pressure class, chemical resistance, connection and dimensions correspond to the conditions of use. There must be a straight piece of pipe of at least 5x the nominal diameter before and after the swing check valve.

Direct assembly on the pump flange is not recommended. Pulsing flow conditions and pressure shocks in the pipe system should be avoided. If the flow is vertical, installation is permitted only if the valve can open upwards; the ring bolt must point upwards if the check valve is installed horizontally. The flow direction of the check valve must be observed (see arrow on the identification plate). During a subsequent pressure test, the seal of the connections must be checked.
