Lightweight, compact, and wafer-type check with excellent water hammer prevention performance
This wafer type valve uses two semicircular valve bodies and a spring as its operating part. It is significantly slimmer than conventional swing checks. Furthermore, its quick and reliable operation prevents water hammer, ensuring the safety of piping lines.
Lightweight, compact and slim body
Compared to JIS standard swing checks, the face-to-face distance is about 1/4 and the weight is about 1/5. It does not take up much installation space and piping work is easy, so it also has excellent cost performance.
