Check Valve Stockist In China
A check valve is an automatic valve whose main function is to prevent fluid (such as liquid or gas) from flowing in the opposite direction in a pipeline. It is also called a non-return valve, one-way valve or reflux valve. It achieves one-way conduction through the deadweight of the valve disc or the pressure of the medium, ensuring that the fluid only flows in the preset direction.

The core components of the check valve include the valve body and the opening and closing parts (circular valve disc). The valve disc is automatically opened and closed by gravity or medium pressure. When the fluid flows forward, the medium pressure pushes the valve disc open; when the flow stops or flows in the reverse direction, the valve disc closes quickly to block the backflow. Shengtian Group provides various types of check valves.
