soft seated check valve Description
Soft-seat check valve is a type of check valve that uses elastic seals (such as rubber and fluoroplastics) to replace traditional metal hard seals. Its core design improves sealing reliability through the embedded soft seat structure, which is especially suitable for industrial scenarios with medium pressure fluctuations or particle erosion.
Valve seat structure: An installation groove is set on the valve seat sealing surface, and the seal is embedded in an interference fit manner, so that the sealing surface and the valve disc form an elastic contact, reducing the minimum medium pressure required for closing; Sealing principle: During forward flow, the medium pressure pushes the valve disc open, and during reverse backflow, the valve disc presses the soft valve seat under its own weight or spring action to achieve face sealing to block backflow.

Material matching
Seals: PTFE or EPDM for corrosive media, graphite-filled fluororubber for high-temperature scenarios; Valve body: Carbon steel for normal working conditions, 316L stainless steel or duplex steel for highly corrosive environments. Installation specifications
When installing horizontally, ensure that the valve disc rotation axis is perpendicular to the fluid direction (swing type); Flush the pipeline before installation to prevent welding slag from scratching the soft sealing surface. Maintenance cycle
Check the wear of the seal every 12 months and replace the soft seal embedded in the groove in time.
