Main Applications

Applicable to various high-pressure medium delivery pipelines in the chemical, metallurgical, petroleum, pharmaceutical and other industries.

Working Principle

When the handle or actuator drives the valve stem to rotate, the ball rotates accordingly.

There is a through hole on the ball. When the through hole is in the same direction as the pipeline, the valve is in an open state;

Conversely, when the ball rotates 90 degrees and the through hole is perpendicular to the pipeline, the valve is closed, thereby cutting off the fluid channel.

Since the sealing surface between the ball and the valve seat is line contact or surface contact, it can maintain good sealing performance even under high pressure conditions.
