Product Overview
The KOZO GS-C25 Lift Check Valve is designed to prevent reverse flow in DIN/EN industrial piping. Forward flow lifts the disc from the seat; when flow decreases or reverses, the disc returns to the seat automatically.
Key Design Features
- Lift-disc non-return design: Automatic operation without an actuator.
- GS-C25 cast-steel body: Industrial DIN/EN material family.
- Compact axial disc movement: Suitable for clean fluids and controlled flow conditions.
- Flanged or welded configurations: Connection options according to piping specification.

Selection Notes
Lift check valves require sufficient forward velocity to raise the disc and should be selected with attention to pressure drop, orientation and minimum flow conditions.
