Twin Plate Check Valve
Wafer check valves (also referred to as twin-plate or duo check valves) are automatic self-acting valves that allow flow in one direction and prevent reverse flow, comprising of two semi-circular plates that are sprung loaded.
These valves are designed for clean water handling, with the plates positioned in the flow path and third-party WRAS approval.
Our dual plate check valves are available in a variety of seat, shell and plate materials to suit demanding applications up to 100°C.
