All About Pneumatic Actuators Types, Applications, and Uses

2 天前· For valve actuation, both on/off and control, air provides a reliable, safe, economical method. Discounting the cost of furnishing compressed air itself, air actuators are usually more cost-effective than electric actuators up to a certain diameter valve. As valves become larger, the economics begin tilting more in favor of electric actuators.
