Product Description

Introduction to check valve

Check valve is a kind of valve that relies on the flow of the medium itself to automatically open and close the valve disc, which is used to prevent backflow of the medium. It is also called check valve, one-way valve, backflow valve, and back pressure valve. Its main function is to prevent the backflow the medium in the pipeline, to prevent the pump and the driving motor from reversing, and to release the medium in the container.
The working principle of the check valve is on the flow direction of the fluid. When the medium flows in the specified direction, the valve disc is opened under the action of the fluid pressure; conversely, when the medium to backflow, the valve disc is automatically closed under the action of the fluid pressure and its own gravity, thus blocking the reverse flow of the medium

The advantages of check valves

1. Prevents backflow of medium
2. Automatic operation without external control
3. Protects equipment and system safety
4. Relatively simple structure easy maintenance
5. Wide range of applications
6. Helps maintain stable system pressure
7. Low flow resistance (some types)
8. Good sealing
