One or two piece threadPneumatic ball valve overview: The pneumatic two-piece internal threaded ball valve is composed of a double (single) acting pneumatic piston actuator and an internal thread (butt-welded) ball valve. The valve body can be divided into integral type, two-stage type and three-stage type. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally increased in pressure, the valve stem will not be impacted. The pneumatic piston actuator adopts low-friction materials to make the bearing sleeve, and the inner and outer surfaces of the cylinder are treated with hard anodized anti-corrosion, which greatly improves the service life of the cylinder. This product has stable performance and is widely used in petrochemical, metallurgical, electric power, light industry, pharmaceutical and other industrial sectors.

2. The main features of the two-piece threaded pneumatic ball valve:
1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe section of the same length.
2. Simple structure, small size and light weight.
3. It is tight and reliable. At present, the sealing surface material of the ball valve is widely used in plastics and has good sealing performance. It has also been widely used in the vacuum system.
4. It is easy to operate and open and close quickly. It only needs to rotate 90° from fully open to fully closed, which is convenient for remote control.
5. The maintenance is convenient, the pneumatic ball valve has a simple structure, the sealing ring is generally movable, and it is convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes.
7. It has a wide range of applications, with a diameter ranging from a few millimeters to a few meters, and can be applied from high vacuum to high pressure.
