Check Valve Manufacturers and Suppliers - China Check Dual Plate Check Valve. The dual-plate check valve opening and closing member is opened or closed by the medium flow and the force to prevent the back flow of the valve from being called a check valve. Check valves are automatic valves, mainly used on pipes with one-way flow of media, allowing only
China API 594 Dual Plate Wafer Type Check Valve - China Dual plate valves are available in various body styles that include wafer, lug, and flange; some meet the popular API 594 face-to-face dimensions. Dual plate valves require removal from the line to perform inspection or repair.
Nov 03, 2019 · Dual Plate Check Valve An all-purpose non return valve that is much stronger, lighter in weight and smaller in size compared to a conventional swing or lift check valve Employs two-spring-loaded plates hinged on a central hinge pin. When the flow decreases, the plates close by the action of torsion spring before flow reversal takes place.

When to Use a Swing Check vs Wafer Check Valve Aug 07, 2015 · When it comes to check valves, swing checks and wafer checks are actually similar in many ways. Both serve to block back flow from occurring in a pipe line. Both use a swinging disc to block and allow flow in one direction. The differences in the two valve may seem obvious when you look at them, but many users don't realize the difference it might make in their application.
