• Double Acting (DA) - Pneumatic actuator that requires a pneumatic signal to turn it on and a second signal to turn it off. Advantage: Fast operation and low cost
• Single Acting (SA) - Pneumatic actuator with spring return that requires one signal to operate. Advantage: In the event of air failure the spring will 'Fail Safe'
• Electric Actuated - Motor and gearbox drive - power open and power close. Slower acting (15-25 seconds). Advantage: Where no compressed air is available

Typical applications are - water and wastewater treatment, water trucks, pneumatic reticulation, cooling towers and agricultural spraying.
