Pneumatic actuated Ball Valve | Regent Regent’s range of pneumatically controlled ball valves, which are 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. The ball valve can be 2-way or 3-way and offers good sealing properties. Pneumatic actuators are a reliable solution and often used to control larger valves than electric actuators at a lower investment cost. There are various housings and sizes of pneumatically controlled ball valves. Contact Regent to allow you to find the right one for your application. In Pic.
