Standard sealing element is a soft seat of Perbunan. Metal to Metal
sealing is also available on request. Check Valves Type C Are not recommended for
pulsating flow conditions. For such applications we recommend Check Valves Type CS.
When installing the Check Valve on the delivery side do not assemble it
directly on to the pump flange or on to a following bend or elbow. The Valve may be fitted
at a distance of 7 to 10 times the nominal width from the beginning of the stabilizing
zone.
