Dual Plate Watercheck Valve

Dual plate wafer check valves are high performance non-slam check valves. The dual plate design is stronger, lighter and smaller compared to a normal swing check valve or non-slam check valve. It also has the advantage of no water hammer. It’s a maintenance free valve with a long life-time.

Available in a size range from 2” to 36” and an ANSI class range of 150-2500.
