The check valve refers to a valve that automatically opens and closes the valve flap by means of the flow of the medium itself, and is used to prevent the back flow of the medium, which is also called a check valve, a check valve, a reverse flow valve, and a back pressure valve. The check valve is an automatic valve whose main function is to prevent back flow of the medium, prevent the pump and drive motor from reversing, and discharge the container medium.
According to the structure, check valve can be divided into three types:
1. Lift Check Valve: Lift check valves are available in both vertical and straight versions.
2. Swing Check Valve: The swing check valve is divided into three types: single-lobed, double-lobed, and multi-lobed.
3. Butterfly Check Valve: The butterfly check valve is divided into a butterfly double flap and a butterfly single flap.
The above several check valves can be divided into four types: a screw connection, a flange connection, a welding and a clip type connection.Yuzheng Valve Co.,Ltd is a professional Check Valve Manufacturer China, we provide you with a variety of valves.
