The Air Actuated Butterfly Valve is a sanitary valve designed for product regulation in sanitary processing industries. Pneumatic valves use air pressure to open and close the valve. They are reliable, have a fast response, and are spark-free. The pneumatic actuated butterfly valve is a versatile product that is the perfect addition to various processes, be it with a batch controller or an automated processing system. With a variety of materials, sizes, and actuator styles it is easy to find the perfect actuated butterfly valve for your system. If you have any questions or wish to place an order for a specialty size or material, please contact our sales team.

Butterfly Valve Actuator Types
Dual Acting Vertical Canister Actuator
Air-to-air acting vertical canister actuators use air from both sides to control the valve. In case of a malfunction the valve will remain in its most recent position.
Spring Return Actuator
Spring return actuators use a spring to maintain a default position and pressurized air is applied to move the valve from this default position.
Spring Return Actuator - Normally Closed
A normally closed actuator's default position is closed, in case of a failure the valve also failsafe closed. This actuator style is ideal for applications where the product line must remain closed in case of failure, such as the outlet on the bottom of a tank or a water-filling line.
Spring Return Actuator - Normally Open
A normally open actuator's default position is open, in this case, the valve will failsafe with the valve open. This actuator style is ideal for applications where the product must exit in the case of a failure, such as an overflow valve.
