Swing Check Valve Class150-2500, 1/2"～60" Carbon Steel , Stainless Steel

Check Valve, also known as a Non-return Valve. This is an automatic valve when it is automatically opened or closed by the force generated by the medium flowing within the pipeline. Its major function is to prevent the backflow of the medium in the pipeline, reverse rotation of the pump and its driving motor, and discharge of the medium in the container. Zaval supplies a complete range of swing check valves with both internal and external hinge pin types. External control devices such as damping, locking, and manual override are part of our expertise.
