Pneumatic Ball Valve Actuator

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
• Limit switch available
