Check Valve basic knowledge revealed, come and learn

The Check Valve is opened and closed by a ball with a circular through hole, and the ball is rotated along the center line of the valve to open and close the Universal Valve. The special compression molding process is used to make the sealing surface dense and good. The V-type PTFE packing combination ensures zero leakage of the Universal Valve. The ball and valve disc are cast in one piece, which eliminates the possibility of the valve rod escaping from the pressure component due to pressure changes, basically ensuring safety during use. It adopts all-plastic lining technology and is resistant to strong corrosion from media.

1. The Check Valve adopts fluorine plastic bottom layer, which has extremely high chemical stability and is suitable for any highly corrosive chemical medium.
2. Adopt an all-pass floating Check Valve structure to detect original leakage within the entire pressure range, and perform ball sweeping and pipeline maintenance through the pipeline system.
The structure of the Check Valve is full-bore floating ball type (two-stage type) and full-bore fixed ball type (three-stage type) (small diameter is two-piece type, large diameter is three-piece type). It is mainly used for cutting off or connecting It can pass corrosive media in pipelines and can be used for the regulation and control of fluids. Compared with other valves, it has the following characteristics:
1. The fluid resistance is small, the inner wall of the lined Check Valve is smooth, and the flow channel is unobstructed. It has the smallest fluid resistance among all valves.
2. The switch is quick and convenient. You only need to rotate the ball 90° to complete the account opening and closing actions.
3. The ball and the Valve Stem are integrated, eliminating the rotation angle difference and eliminating the risk of the valve stem rushing out of the body due to pressure changes, ensuring the safety and reliability of use.
