The Dual Disc® Check Valve with its compact wafer design and low cost have made it a popular choice when space and price are major factors in valve selection. The compact design features non-slam spring-assisted closing.
Champion wafer check valves are designed for installation in flanged piping systems, between two flanges. Valves may be installed in vertical or horizontal piping.
Care must be taken to always install the valves with the shafts in a vertical position when installing in a horizontal pipeline. Vertical up flow is always a good installation. Consult factory for vertical down flow. Champion wafer check valves are designed to provide long service life if the velocity is kept within the flow rate shown in the table on page 7 and if a minimum of 5 pipe diameters of straight pipe in front of the valve is maintained downstream from a likely cause of turbulence (i.e., pump discharge, reducers or elbows).
