Swing Check Valve With Counter Weight Introduction
Swing check valve is a valve used to prevent the medium from flowing backwards. It relies on the flow of the medium itself to automatically open or close the disc. The main function of the swing check valve is to prevent the medium from flowing backwards, protect the pump and drive motor, and avoid medium leakage in the container.

Swing check valve with counter weight is characterized by a heavy hammer installed on the valve disc, which can adjust the opening angle and closing speed of the valve disc, thereby reducing the water hammer phenomenon and pressure loss. The counterweight can be adjusted according to different working conditions to achieve the best working effect.
