Product Overview
The KOZO CF8M Dual Plate Wafer Check Valve is designed for compact non-return protection where installation length and weight are important. Two spring-assisted plates open with forward flow and close as velocity decays, providing a shorter travel than a conventional swing disc.
Key Design Features
- Dual-plate spring-assisted design.
- ASTM A351 CF8M stainless-steel body family.
- Compact wafer installation between pipeline flanges.
- Metal or resilient seat options according to service.
- API 594 design family.

Selection Notes
Seat temperature limits must be based on the actual elastomer or metal-seat design. System velocity and pressure transients should be checked when selecting check-valve size.
