Operation Principle
Spring Return Actuators
Air pressure forces pistons outward, compressing springs and rotating pinion counterclockwise. Upon pressure loss, stored spring energy returns pistons inward, rotating pinion clockwise for reliable fail-safe operation.
Customization Options
Available with various coating options including PTFE, Nickel, Epoxy, Polyester and Ceramic for corrosive environments. Multiple color choices for end caps (blue, black, grey, yellow).
