Rotary Actuator

Rocking Piston: The unique design of the MASCOT rotary actuators features a “rocking” piston with a fixed connection at the shaft arm rather than a scotch yoke mechanism or a rack and pinion mechanism which are both prone to backlash making this actuator the preferred choice for control applications.
High Torque Cylinder: Operating pressure of up to 150 psi (10.3 Bar) results in a substantially higher torque capability compared to diaphragm actuators resulting in achieving a tighter shutoff for the valve.
Low Deadband & Excellent Positioning Accuracy: Double-acting configuration responds quickly to signal changes and provides high repeatability and low hysteresis.
Lightweight & Compact: The Actuator is substantially lighter and more compact than comparable rotary diaphragm actuators which offers ease of maintenance.
Adjustable Stops: Adjustable stroke stops prevent excessive rotation and reduce excessive torque on shaft. They also act as mechanical limit stops to mechanically limit the control valve’s travel for safety considerations.
Low Air Consumption: Cylinder design uses less supply air than comparable diaphragm actuators resulting in lower operating cost for the plant.
Ease of Maintenance: Periodic maintenance is easy to perform since the spring cylinder actuator only requires the removal of three parts to access all internal parts. Moreover the actuators are fully field reversible without the need for any additional parts.
