Collection:Pneumatic Ball Valves

Explore Tameson's wide range of pneumatic ball valves from leading global manufacturers. Pneumatic ball valves control the flow of media - liquids or gases - using a rotating ball with a bore. A pneumatic actuator connects to the valve and converts compressed air into mechanical motion, rotating the ball 90° (a quarter turn) to open or close the valve.

A pneumatic ball valve consists of two main components: the pneumatic actuator and the ball valve. These are typically mounted together using a standard ISO 5211 flange, which lets you swap either the actuator or the valve for another with the same flange size.

A pneumatic actuator is either single-acting or double-acting. A single-acting actuator, also known as fail-safe, uses compressed air to rotate the ball in one direction and a spring to return it to its normal position if air pressure is lost. A double-acting actuator requires compressed air to move the ball in both directions. For larger valves, pneumatic actuation is often more cost-effective than electric actuation.

Pneumatic ball valves are available in a range of housing materials and sizes to suit different applications. They're commonly used to remotely control fluid flow, such as in water lines or compressed air systems.
