1000PSI PN64 2PC Ball Valve

The 1000PSI PN64 2PC Ball Valve produced from JOEPAI features a full bore design that ensures unrestricted flow with minimal pressure loss, combining full bore flow with high pressure tolerance. It is highly suitable for strict industrial applications, meets global thread standards, and can resist corrosion, and high temperature stress.

Product Detail：

Two piece ball valve, also known as quick opening ball valve, internal thread ball valve, or small ball valve. 

Working Principle

1、 Opening process

In the closed position, the ball is tightly pressed against the valve seat by the mechanical pressure exerted by the valve stem.
When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and its bottom angular plane causes the ball to detach from the valve seat.
The valve stem continues to lift and interacts with the guide pin in the spiral groove of the valve stem, causing the ball to start rotating frictionlessly.
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.

2、 Closing process

When closing, rotate the handwheel clockwise and the valve stem begins to descend, causing the ball to move away from the valve seat and begin to rotate.
Continuing to rotate the handwheel, the valve stem is subjected to the action of the guide pin embedded in its spiral groove, causing both the valve stem and the ball to rotate 90 ° simultaneously.
When it was about to close, the sphere had already rotated 90 degrees 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 and presses the ball tightly against the valve seat, achieving complete sealing.
