General Description
Dual Plate Wafer Check Valves have been the preferred choice for decades due to their proven reliability and low pressure drops.
Features
-Low Pressure Drop
Dual plate wafer check valves have larger open area than other designs, thus reducing pressure drop compared to swing, lift or other check valves.
-Light Weight
Reduces weight by 80–90% compared to conventional Flanged check valves.
-Lower Cost
Light weight, compact profiles and the elimination of flanges allows Dual plate Wafer check valves to be manufactured more economically than other designs, especially as pipe diameters increase.
-Alleviates Water Hammer
Our spring activated discs are designed to close our valves quickly. This assures high performance, eliminating chatter and creating dynamic responsiveness in a non-slam design.
-Simple Installation
Easier to install, remove and replace in both new and existing piping systems.
