About High Pressure Ball Valve

The ball of the high-pressure ball valve is floating. Under the action of the medium pressure, the stainless steel valve can generate a certain displacement and press against the sealing surface at the outlet end to ensure the sealing of the outlet end.

The valve has a simple structure and good sealing performance, but the load of the ball subjected to the working medium is all transmitted to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the spherical medium, and when subjected to a high pressure impact. The sphere may be offset.

This type of structure is generally used for medium and low pressure ball valves.


1 The bottom-loading valve cymbal is used to provide an inverted seal structure to ensure reliable sealing of the packing.

2 The movable metal valve structure preloaded by the leaf spring has reasonable sealing force design, flexible opening and closing, and reliable sealing.

3 According to the needs of users, it can be designed to be suitable for structures containing medium particles, materials, etc., or structures with high temperature resistance.

Working principle:

The high pressure ball valve has a motion of 90 degrees of rotation, the body of the plug is a sphere, with a circular through hole or passage through its axis. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. It only needs to be rotated 90 degrees and the torque can be closed tightly.

The main features of the high-pressure ball valve are its compact structure, reliable sealing, simple structure and convenient maintenance. The sealing surface and the spherical surface are often closed, not easily eroded by the medium, easy to operate and maintain, suitable for water, solvent, acid and natural gas. Working medium, but also suitable for media with poor working conditions.

The ball valve body may be integral or combined.


The product is classified into a metal seal and a soft seal according to its sealing performance. The utility model has the advantages of compact structure, small volume, reliable operation, good sealing performance, easy maintenance, convenient installation and strong adaptability. Particularly suitable for occasions where the medium is viscous, granule-containing, or fibrous.


Can be widely used in petroleum, chemical, teaching equipment, light industry, high-voltage equipment, pharmaceutical, paper and other industrial automatic control systems for long-distance centralized control or local control.
