3-Piece Thread Pneumatic Ball Valves

Description of Pneumatic Three-Piece Ball Valve

Pneumatic three-piece ball valves are divided into integral type, two-stage type, and three-stage type. The casting of the valve body adopts the technology imported from Taiwan, with a reasonable structure and a beautiful appearance. 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 a reverse seal, and the valve stem will not be impacted when the valve chamber is abnormally boosted. A 90° switch positioning mechanism can be set and locked as needed to prevent misuse.

Features Of 2 Way Pneumatic Ball Valve

The fluid resistance is small, and the full-bore ball valve has no flow resistance.

The pneumatic ball valve has a simple structure, small in size, and is lightweight.

Tight and reliable. It has two sealing surfaces.

Easy to operate, fast opening and closing, only need to rotate 90° from fully open to fully closed, which is convenient for long-distance control.

Easy maintenance, the structure of the ball valve is simple, the sealing ring is generally movable, and it is more convenient to disassemble and replace.

When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface

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.

Since the ball valve has wiping properties during opening and closing, it can be used in media with suspended solid particles.
