Penglai Huande Steel Valve Co., Ltd exports precision casting floating ball valves. Our 2 piece internal ball valves are produced by the craftwork of wax injection and de-wax. In every process, our products are checked by trained employees so that we can guarantee the good quality of our products. Usually, we use the material of CF8M, CF8, WCB, 304 to produce 2 pc internal ball valves. The Size is from DN8 to DN50. It can be widely used in petroleum, chemical, food, medicine, railway, water treatment, steel, metallurgy and other industries.

The operating processes are as follows:

Open process:
In the closed position, the ball is pressed by the valve stem and pressed against the valve seat. When the handwheel is turned counterclockwise, the valve stem moves in the opposite direction, and its bottom angular plane disengages the ball from the valve seat. The stem continues to lift and interacts with the guide pin in the spiral groove of the stem, causing the ball to begin rotating without friction. Until the fully open position, the stem is raised to the extreme position and the sphere is rotated to the fully open position.

Close process:
As the handwheel continues to rotate, the valve stem is acted upon by a guide pin embedded in the helical groove thereof, causing the valve stem and the ball to rotate by 90° at the same time. When closed, rotate the handwheel clockwise and the stem begins to lower and the ball moves away from the seat. When it is about to close, the ball has rotated 90° without contact with the valve seat. For the last few turns of the handwheel, the angular plane at the bottom of the valve stem is mechanically wedged against the ball so that it presses tightly against the valve seat and is completely sealed.
