Pneumatic linear actuators contain a rolling diaphragm with internal springs and have a low height and low friction. The fail-safe action is easily reversed in the field with no extra parts by inverting the diaphragm and switching the direction of the air supply. Actuators fit on a yoke and are designed to sit directly over the valve enhancing the compact design of the valve assembly.
Pneumatic rotary actuators are designed to open at a 70° angle for throttling applications and 90° angle for on/off applications. The actuators can be ordered with manual override. SAMSON offers rack & pinion, piston, and diaphragm rotary actuators.
Electric actuators have optional electric or mechanical override and can be ordered with fail-safe action.
