W45/W45 HMP Spring Disc Check Valves
W45 Spring check valves are used to stop or "check" reverse flow in a pipeline. The W45 series of check valves use a disc or "wafer" where product flow pushes the valve disc away from the seat. In the absence of forward flow, the disc holds closed against the seat. Back flow pressure also pushes the disc into the closed position.
Features
- Positive o-ring seal and metal-to-metal seating for robust, "soft seat" closure
- Limited Stroke to prevent over-compression: improves spring life, reduces stem wear, improves cleanability
- CIP capabile, 3-A design in 1"-4"
- Machined from bar 316LSS body w/ 32 Ra or better polish
