How does a pneumatic actuated ball valve work?

What is a pneumatic ball valve?

Pneumatic ball valve is a combination of ball valve and pneumatic actuator, and it is a spherical valve controlled by pneumatic device.
A pneumatic actuator refers to a device that controls a valve and generates torque through a power source to control or operate a ball valve.
A ball valve is a tool or device that controls the medium through a hollow rotating ball, which can help regulate the flow of the medium.

The working principle of the pneumatic actuated ball valve is to use the ball as a closing element to control the circulation or cut off of the medium by rotating the ball.

What are the components of the pneumatic ball valve?

1. Valve body: usually made of metal material with high strength and corrosion resistance. There is a ball hole inside the valve body for placing a ball.

2. Ball: the core part of the pneumatic ball valve, usually through the spherical hole through the ball to achieve fluid on-off control. Balls are usually made of metallic materials such as stainless steel, cast iron, etc.

3. Sealing structure: There is a sealing structure between the ball and the valve body to ensure the sealing performance of the valve. The most common sealing structures are packing seals and elastic seals.

4. Pneumatic device: The pneumatic device can be driven by air or gas pressure, and the ball can be rotated by applying pressure to the pneumatic device to realize the switch control of the valve.

What are the benefits of using a pneumatic ball valve?

1. Quick response and control: The pneumatic ball valve can open and close quickly to achieve fast and accurate fluid control.

2. High reliability and long life: The pneumatic ball valve has simple structure, reliable operation, and is made of corrosion-resistant materials, with a long service life.

3. Good sealing performance: The pneumatic ball valve adopts packing seal or elastic sealing structure, which can effectively prevent medium leakage and improve the safety and reliability of the system.

4. Applicable to large caliber range: Pneumatic ball valves are suitable for various caliber ranges, and can handle large flow media to meet the needs of different applications.

5. Automation and remote control: The pneumatic ball valve can be integrated with the automatic control system to realize remote monitoring and automatic operation, and improve the intelligence level of the process system.
