A ball valve is a valve with a spherical disc, the part of the valve which controls the flow through it. High Pressure High Temperature Ball Valve is widely used in the petroleum refining, long-distance pipelines, chemical, paper, pharmaceutical, water conservancy, electricity, municipal, and steel industries in the national economy occupies a pivotal position. High pressure ball valve is mainly used to cut off or turned on the line of media can also be used for the regulation and control of the fluid, V-hard seal ball valve V-ball core surfacing carbide metal seat has a strong the shear force, especially suitable for containing fibers, a tiny solid particles such medium. Multi-way ball valve in the pipeline, not only flexible control of the confluence of the media streaming and switch the flow direction, but also to close any one channel the other two channels connected.

Operation and use of high-pressure ball valve:

1, the operation required to confirm before piping and valves have been washed off.

2, the operation of the valve input signal size by executing agency driven stem rotation is complete: Forward rotating 1/4 turn (90 °), the valve off. The reverse rotating 1/4 turn (90 °), the valve opens.

3, when implementing agencies directional arrows parallel with the pipeline, the valve is open; indicator arrows and vertical pipelines, valves off. There are five general body styles of ball valves: single body, three piece body, split body, top entry, and welded. The difference is based on how the pieces of the valve—especially the casing that contains the ball itself—are manufactured and assembled. The valve operation is the same in each case.
