Stainless steel three-way ball valve principle:

In the stainless steel three-way ball opening process

1, in the closed position, the ball is mechanically pressed by the stem, tightly pressed on the seat.

2, when the handwheel is turned counterclockwise, the stem is reversed, and its bottom angular plane makes the ball disengage the seat.

3、The stem continues to lift and interact with the guide pin in the spiral groove of the stem, so that the ball starts to rotate without friction.

4, until it reaches the fully open position, the valve stem is lifted to the limit position, and the ball rotates to the fully open position.

When the stainless steel three-way ball closing process

1、When closing, rotate the handwheel clockwise, the valve stem starts to descend and make the ball leave the seat and start to rotate.

2, continue to rotate the handwheel, the valve stem by the role of the guide pin embedded in its spiral groove, so that the stem and the ball simultaneously rotate 90 °.

3、When it is about to close, the ball has rotated 90° without contact with the seat.

4、The last few turns of the handwheel rotation, the angular plane at the bottom of the stainless steel three-way ball valve stem mechanically wedges to compress the ball, so that it is closely pressed against the seat to achieve a complete seal.

Stainless steel three-way ball valve structural features:

Top-loading structure:

Stainless steel three-way ball valve installed in the pipeline can be directly online inspection and maintenance, can effectively reduce device parking, reduce costs. This type of valve in the pipeline should generally be installed horizontally.

Frictionless opening and closing:

Completely solve the traditional valve due to the sealing surface friction between each other and affect the sealing problem.

Low torque design. Special structure design of the stem, only a small handle valve can be easily opened and closed.

Wedge seal structure. The valve is sealed by the mechanical force provided by the stem, which presses the ball wedge onto the seat, so that the valve sealing is not affected by the change of differential pressure in the pipeline, and the sealing performance is reliably guaranteed under various working conditions.

Single seat design. Eliminate the valve cavity medium due to abnormal pressure rise and affect the safety of the use of the problem.

Self-cleaning structure of the sealing surface. When the ball is tilted away from the seat, the fluid in the pipeline along the ball sealing surface into 360 ° uniform passage, not only eliminates the high-speed fluid on the seat local scouring, but also flush away the accumulation of sealing surface, to achieve the purpose of self-cleaning.
