Wafer check valve‌, also known as counterflow valve, check valve, back pressure valve or one-way valve, is a valve that automatically opens and closes by relying on the flow of the medium itself. Its main function is to prevent the backflow of the medium, protect the pump and drive motor from reversing, and prevent the release of the medium in the container.

Wafer check valve has the following structural features:

‌Small fluid resistance‌: The fluid resistance of the valve is small and has little impact on the flow of the medium.

‌Good sealing performance‌: It has good sealing performance to ensure that the medium will not flow back.

‌Simple structure‌: Simple design, easy to manufacture and maintain.

‌Small size‌: Compact structure, small space occupied.

‌Easy to maintain‌: Maintenance and maintenance are relatively easy.

‌Wide range of application‌: Suitable for various pipeline systems, including high temperature, high pressure and low temperature pipeline systems‌.
