Check Valves
Check valves operate in a one-way direction to prevent process flow from reversing in air and gas systems. Flow in the desired direction opens the valve, while backflow forces the valve closed. Our wafer-style swing check valve features a balanced disc where only 33% of the disc area is unbalanced. This is considerably less than conventional check valves. This feature tends to reduce back-flow and eliminate slamming (a major factor in valve failure), and permits the disc to open with a minimum of pressure differential.
Competitively priced, our Check Valve's simple design, quality construction, and consistent operation makes it an industry best buy.
