Dual Plate Wafer Type Check Valves
The Dual Plate Wafer Type Check Valve is designed to prevent reverse flow in piping systems while offering a compact, efficient solution for industrial applications. Its dual-plate design ensures rapid closure with minimal water hammer, protecting downstream equipment and enhancing system longevity.
This valve is highly effective for reducing flow reversal in liquid and gas systems. With pressure ratings of Class 150# and 300#, it is suited for moderate and high-pressure systems, offering low pressure drop and energy-efficient performance. The wafer-type construction allows for easy installation between flanges, saving space and weight in comparison to conventional swing check valves.
