ZHMWS-A1 WCB Body Check Valves Flanged End FAQs

Q 1. What is a Check Valve?

A check valve refers to a valve whose opening and closing parts are circular discs and rely on its own weight and medium pressure to block the backflow of the medium.

Q 2. How Do Swing Check Valves Work?

The swing check valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. It belongs to an automatic valve. The function of the swing check valve is to prevent the medium in the pipeline from flowing back. Check valves belong to the category of automatic valves, and the opening and closing parts are opened or closed by the force of the flowing medium. The check valve is only used in the pipeline where the medium flows in one direction to prevent the medium from returning to prevent accidents.
