We use wax injection and de-wax craftwork to produce the precision casting 1 PC internal thread reduced bore ball valve, which allows the product with zero detect and sells well in the global world. Usually, we use the material of 304 to produce the handle, stopper,nut spring washer and the stem packing, thrust washer is produced by the PTFE. The thread ends can be produced according to the JIS, DIN, ANSI and other standards. The size is from DN8 to DN50.

The Function of 1 PC Internal Thread Ball Valve:

1. The fluid resistance is small, and its drag coefficient is equal to the length of the same length.
2. It has a simple structure, small size, lightweight.
3. It is closed and reliable, the current ball valve sealing surface materials are widely used in plastics. It has good sealing properties, and it is widely used in vacuum systems.
4. It is easy for customers to operate, fast opening and closing, as long as the rotation from 90 degrees from fully open to fully closed, it can be easy remote controlled.
5. Easy maintenance, the ball valve structure is simple, the seal ring is generally active, removal and replacement are more convenient.
6. When fully open or fully closed, the sealing surfaces of the ball body and the valve seat are isolated from the medium. When the medium passes through, the sealing surface of the valve will not be eroded.
7. A wide range of applications, from small to several millimetres in diameter, up to a few meters in size, from high vacuum to high pressure can be applied. When the ball is rotated 90 degrees, all the spheres at the entrance and exit should be spherical, thus cutting off the flow.
