Pneumatic ball valve working principle

Pneumatic Ball Valve is composed of pneumatic actuator and ball valve, replacing manual operation, not only saves a lot of manpower and material resources, but also can control multi-ball valve. Pneumatic Ball Valve actuator to work with the valve body can quickly open and close, the speed can be cut off in seconds. Pneumatic actuator’s execution speed is relatively fast, the fastest switching speed 0.05 seconds per turn, so usually also known as pneumatic quick-cut ball valve. Pneumatic Ball Valve pneumatic actuator is divided into single-acting, double-acting two, in the pneumatic head with accessories such as: Three pieces, positioner, limit switch, etc. , can be used as throttling regulation flow. At the same time with the control box, you can control the switch in the remote control room. 

Pneumatic Ball Valve only through the Compressed air into the pneumatic actuator, the air source drive ball core rotation 0-90 degrees operation and a very small torque can control the ball valve switch, the valve positioner can be assembled according to the working conditions, so as to control the opening of the ball spool of the ball valve to adjust the medium flow. The ball is rotated around the center line of the valve body to open a circular through hole or channel through its axis. When the BALL CENTER ROTATES TO 90 & DEG; , the Valve is in a closed state, when the actuator works, only a small torque can close the valve tightly, thus achieving the principle of rapid cut-off.

Pneumatic ball valve structure classification:

pneumatic ball valve according to the structure difference can be divided into on-off pneumatic ball valve and regulating pneumatic ball valve, on-off type only open and close two actions, and regulating type can control the flow size!

1. The Valve Spool of the switch type pneumatic ball valve is generally o type ball Spool, the o Type Ball Valve Spool is floating type precision casting, the runner mouth and the pipeline caliber are the same, is mainly uses as the cut-off switch.

2. The valve core of the adjustable pneumatic ball valve is a v-shaped ball core with a fixed structure and a v-shaped notch on the ball core
