Lightweight, compact wafer-type check valve with excellent water hammer prevention performance

This wafer-type product uses two semi-circular discs and springs for the operating component. Compared with conventional swing check valves, this allows for a drastically slimmer design. In addition, the responsive and reliable operation helps prevent water hammer. This ensures the safety of the piping lines are maintained.

Lightweight, compact design with a slim profile

Compared with other JIS-compliant swing check valves, this valve has one-fourth the width and one-fifth the mass. Because there’s no need to ensure extra installation space, and piping work is simple, the valve provides excellent cost performance.
