View Tameson’s range of pneumatically controlled 3-way brass ball valves, which are used to control the flow of liquids and gases remotely. The actuator will open and close the ball valve with compressed air (single acting uses a spring to either open or close the valve). The ball valve has a hole through one side to allow flow when turned appropriately. These valves are 3-way valves (3 ports) and offer good sealing properties. Available with L-bore or T-bore. Pneumatic actuators are a reliable solution and often used to control larger valves than electric actuators at a lower investment cost. There are various sizes of pneumatically controlled ball valves to allow you to find the right one for your application. The brass valve housing allows it to be used for water, air, oil or other neutral liquid media.
