Features

• Low Pressure Drop (High Cv)
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 check valves to be manufactured more economically than other designs, especially as pipe diameters increase.
• Alleviates Water Hammer
RXVAL spring activated discs are designed to close our valves quickly.This assures high performance, eliminating chatter and creatingdynamic responsiveness in a non-slam design.
• Simple Installation
Easier to install, remove and replace in both new and existing piping systems.
• Retainerless Design
Ideal for critical applications where valve body penetration and the possibility of leakage cannot be tolerated.
