SWING CHECK VALVES (ORCA)
Prevention of Backflow
Hydroseal Canada’s orca Swing Check Valves prevent reversal of flow in larger sized piping systems using swing action. They are ideal for trouble-free backflow prevention in any application. Swing check valves can be used in both horizontal and vertical installations..
Hydroseal Canada Swing Check Valves operate especially well with viscous slurries that may adversely affect other types of check valves. The default position of the valves is closed – line pressure moves the solid wafer seal off its EPDM gasket allowing slurry through the body of the valve. When the inlet flow stops, swing action moves the seal back onto the seat – stopping the flow.
