The HYDAC dependable rack and pinion pneumatic actuators are compact and efficient components with a trouble-free, high-cycle service life.
The double piston design allows significantly reduced cylinder diameter and overall size as compared to single piston design.
Each piston has a gear rack that applies an equal force at two points directly across the diameter of a common pinion gear.
This feature, combined with the patented suspension system, creates a symmetrically balanced, center-mount actuator with a short, powerful stroke, rapid response, and fully concentric operating loads for optimum life expectancy and performance in control valve applications.
Features
Reliable rack and pinion design
High output torque and compactness
Integrated air manifold and internal porting
A solenoid valve can be mounted directly onto actuator body thus external piping is simplified
Double-acting and single-acting (spring return) models are available
Self-lubricating bands reduce friction and smooth piston travel, and increase efficiency
