Direct answer
Use pneumatic actuators when a ball valve or butterfly valve needs remote quarter-turn operation, repeatable automated switching, double-acting control or spring-return fail-safe action.
Quarter-turn valve automation
Pneumatic actuators are commonly matched with ball valves and butterfly valves for automated opening and closing.
Action type
Double-acting actuators use air to open and close. Spring-return actuators can move to a safe position when air pressure is lost.
What to provide
Send valve size, torque or valve model, working pressure, action type, accessory needs, quantity and installation standard.
