Product Overview
The KOZO CF8M Pressure Seal Swing Check Valve is designed for high-pressure corrosive process systems where stainless-steel construction and automatic non-return protection are required. Forward flow opens the disc; reverse flow closes it automatically to help prevent backflow.
Key Design Features
- Pressure-seal closure: Uses internal pressure to increase sealing load at the bonnet joint.
- CF8M stainless body: Reference cast stainless construction for compatible corrosive service.
- Swing-disc operation: Automatic non-return function without an actuator.
- High-pressure family: Available up to Class 2500 depending on configuration.
- RTJ / butt-weld options: Suitable for high-pressure piping systems.

Selection Notes
Disc dynamics, flow velocity, orientation and pressure drop should be evaluated to ensure stable swing-check operation. Temperature limits depend on trim, seat, bolting and the full pressure class.
