Ball valve product series Pneumatic three-piece dental ball plug valve Shoulong ball valve Pneumatic three-piece dental ball plug valve introduction ]Mechanical[/] pressure is pressed tightly on the valve seat. When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction and its bottom angular plane causes the ball to disengage from the valve seat. The valve stem continues to lift and interacts with the guide pin in the spiral groove of the valve stem to cause the ball to begin rotating without friction. Until it reaches the fully open position, the valve stem is lifted to the extreme position and the ball rotates to the fully open position. 2. Closing process When closing, turn the handwheel clockwise, the valve stem begins to fall, and the ball leaves the valve seat and begins to rotate. Continuing to rotate the handwheel, the valve stem is acted upon by the guide pin embedded in the spiral groove, causing the valve stem and the ball to rotate simultaneously. When it is about to close, the ball has rotated without contact with the valve seat. During the last few turns of the handwheel, the angular plane at the bottom of the valve stem mechanically wedges against the ball to press it tightly against the valve seat to achieve a complete seal.
