API Flange-connected manual Check valve

Check valve

Product Overview

Also known as non-return valve or one-way valve, it is a valve with automatic closing function. Its main function is to prevent the backflow of media in the pipeline. When the medium flows in one direction, the valve disc opens under the force of the medium, and the medium can pass smoothly. When the medium flows in the opposite direction, the valve disc quickly closes under the pressure of the reverse medium and the weight of the valve disc to prevent the reverse flow of the medium.

Product Features

1. Good sealing performance: ensure that there is no leakage of the medium and prevent rapid friction and wear of the valve disc.

2. Small fluid resistance: minimize the resistance of the fluid when it flows through the valve.

3. Close quickly: increase the safety and reliability of the system operation

Application range

In various fluid pipeline systems, occasions where it is necessary to prevent the backflow of the medium. Pressurization, exhaust, and circulation systems in water conservancy, electric power, petrochemical, metallurgy and other industries
