Pneumatic ball valve is playing a more and more important role in normal use. It gradually replaces other valve types. This valve type has more advantages.
Aerodynamic ball valve can be closed tightly with only the operation of air rotation and a small torque. The completely equal valve body cavity provides the medium with a small resistance and a straight flow channel. It is generally thought that the ball valve is suitable for direct opening and closing applications, but recent developments have planned the ball valve so that it has the purpose of throttling and controlling flow. The main feature of the pneumatic ball valve is its compact structure, easy to operate and repair, suitable for common operating media such as water, solvents, acids and natural gas, and also for media with harsh operating conditions, such as oxygen, hydrogen peroxide, methane and ethylene.
The pneumatic ball valve body can be whole or combined. The performance of the pneumatic actuator is relatively fast, and does not require workers to do it themselves, which saves human resources and time to a large extent. The pneumatic ball valve is evolved from the plug valve. It has the same rotation degree lifting action. The difference is that the cock body is a sphere and has a circular through hole or channel passing through its axis. The share of the sphere and the passage opening should be such that when the ball rotates 90 degrees, the sphere should appear at the entrance and exit, and then cut off the flow. The pneumatic ball valve only needs to enter the pneumatic actuator through compressed air. The air source drives the ball core to rotate between 0-90 degrees and the small torque can control the ball valve. The opening of the core adjusts the medium flow. The sphere is rotated around the center line of the valve body to achieve opening, and a circular through hole or channel passes through its axis. When the center of the ball rotates to 90°, the valve is in a tightly closed state. When the actuator is working, it only needs a small turning torque to close the valve tightly, so that the principle of rapid cut-off can be achieved.

Aerodynamic Ball Valve

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fast switching speed is 0.05 seconds / time, so it is often called a pneumatic quick-cut ball valve. Pneumatic ball valves are usually equipped with various accessories, such as solenoid valves, air source processing triplets, limit switches, positioners, control boxes, etc., to achieve local control and long-distance centralized control. The valve can be controlled in the control room There is no need to go to the scene or bring manual control at high altitude and dangerously, which greatly saves human resources and time and safety.
Cast iron ball valve manufacturers china reminds you that the aspects of pneumatic ball valve selection need to pay attention to:
1.The working principle of pneumatic ball valve is to open or close the valve by rotating the valve core. The ball valve switch is lightweight, small in size, can be made into a large caliber, reliable sealing, simple structure, easy maintenance, the sealing surface and the spherical surface are often closed, not easily eroded by the medium, and widely used in various industries.
2. Pneumatic ball valve is mainly used in the pipeline to cut off, distribute and change the flow direction of the medium.
3. Pneumatic ball valve is a relatively new type of ball valve. It has some unique advantages of its own structure, such as no friction on the switch, easy sealing wear, and small opening and closing torque. This reduces the size of the actuators. Equipped with a multi-turn electric actuator, it can realize the adjustment and strict shut off of the medium.
