Pneumatic ball valve composition and characteristics

 

 Pneumatic valve manufacturersIt is considered that the pneumatic ball valve is composed of double (single) action pneumatic piston actuator and floating ball valve. It is powered by compressed air, the valve stem drives the valve core in the valve body to rotate 90. This product can be divided into soft seal and metal seal according to its sealing performance. It has the characteristics of compact structure, small size, reliable work, good sealing performance and convenient maintenance. Widely used in petroleum, chemical, light industry, pharmaceutical, paper and other industries of automatic control system.

 

Pneumatic valve manufacturers believe that pneumatic ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Compared with other valves, it has the following advantages.

 

1. Low fluid resistance. Even if it is a decompression ball valve, the fluid resistance is quite small.

2. The thrust bearing reduces the friction torque of the valve stem, which can make the valve stem run smoothly and flexibly for a long time.

 

3. The valve seat has good sealing performance. Sealing rings made of elastic materials such as PTFE are easy to seal, and the sealing capacity of the ball valve increases with the increase of medium pressure.

 

4. The valve stem seal is reliable. Pneumatic valve manufacturers believe that because the valve stem only rotates like a wheel and does not move up and down, the packing seal of the valve stem is not easy to damage, and the sealing capacity increases with the increase of medium pressure.

 

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

 

6. The protruding step of the bottom-mounted stem and stem head prevents the stem from ejecting. If the valve stem seal is damaged by fire, the protruding step can form a metal contact with the valve body to ensure the valve stem seal.

 

7. Anti-static function: there is a spring between the ball, the valve stem and the valve body, which can export the static electricity generated during the switching process.

 

Pneumatic valve manufacturers believe that pneumatic ball valves are composed of ball valves equipped with pneumatic actuators. Pneumatic actuators are divided into double-acting pneumatic actuators and single-acting pneumatic actuators, which are controlled by solenoid valves to open and close the ball valve. Pneumatic ball valve can realize intelligent control, quickly open or close the pipeline, and effectively control and manage the pipe network. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. It only needs to rotate 90 degrees and a small rotation torque to close tightly.

 

  Pneumatic valve manufacturersIt is believed that the working principle of pneumatic ball valve is to open or close the valve by rotating the valve core. The pneumatic ball valve switch is light in weight, small in size, can be made into a large diameter, reliable in sealing, simple in structure, and convenient in maintenance. Its sealing surface and spherical surface are always in a closed state, not easy to be eroded by the medium, and are widely used in various industries. Pneumatic ball valve and plug valve belong to the same type of valve, but its closing piece is a sphere, the sphere around the center line of the valve body to open and close.
