The sealing performance is good, but the ball bears all the load of the working medium and is transmitted to the outlet sealing ring.

Wear resistance; Due to the fact that the core of the hard sealed ball valve is alloy steel spray welded.

In China, ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceut...

A ball valve is a valve whose opening and closing parts (balls) are driven by the valve stem and rotate around the axis of the ball valve.

The butterfly valve has a simple structure, small volume, light weight, and relatively few components.

The main control parameters of butterfly valves are specifications and dimensions.

The installation position, height, and inlet/outlet direction must meet the design requirements, and the connection should be firm and tight.

During installation, the valve disc should be stopped in the closed position.

The rubber elastomer in butterfly valves may experience tearing, wear, aging, perforation, and even detachment during continuous use.

Due to the significant pressure loss of butterfly valves in pipelines, consideration should also be given to the robustness of the butterfly plate ...

The butterfly plate of the butterfly valve is installed in the diameter direction of the pipeline.

The angle from fully open to fully closed of a butterfly valve is usually less than 90 °.
