3 Inch Cryogenic Ball Valve

3 inch ball valve stainless steel 304 316 cryogenic pneumatic ball valve

Pneumatic flange ball valve product features:

　　 1. Gear type double piston, large output torque and small volume.

　　 2. The cylinder is made of customized materials, with light weight and beautiful appearance.

　　 3. Manual operation mechanism can be installed on the top and bottom.

　　 4. Rack connection can adjust opening angle and rated flow.

• The actuator can be equipped with electrical signal feedback instructions and various accessories to realize automatic operation.

Pneumatic ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid adjustment and control. Compared with other valves, it has the following advantages.

　　 1. The fluid resistance is small, and the ball valve is one of the small fluid resistances in all valves. Even if it is a reduced-diameter ball valve, the fluid resistance is quite small.

　　 2. Thrust bearings reduce the friction torque of the valve stem, which can make the valve stem operate smoothly and flexibly for a long time.

　　 3. The valve seat has good sealing performance. The sealing ring made of ammonium PTFE and other ammunition materials is easy to seal, and the valve sealing capacity of the ball valve increases with the increase of the medium pressure.

　　 4. The valve stem is reliable in sealing. Since the valve stem only imitates the rotation and does not move up and down, the packing seal of the valve stem is not easy to break, and the sealing capacity increases with the pressure of the medium.

　　 5. Due to the good self-lubricating properties of PTFE and other materials, the friction loss with the ball is small, so the life of the ball valve is long.

　　 6. The bottom-mounted valve stem and the convex step of the stem head prevent the stem from spraying out. If the seal of the stem is damaged due to fire, metal contact can also be formed between the convex step and the valve body to ensure the sealing of the stem.

　　 7. Anti-static function: Set a spring between the ball, valve stem, and valve body to discharge static electricity generated during the switching process.
