Hydro-Pneumatic Rotary Actuator

TECHNICAL

Tecnair Hydro-Pneumatic Rotary Actuators are manufactured in accordance to individual client specification. This means the overall dimensions can be custom designed to suit the particular application. Contact your local representative for further information.

OPERATIONAL SCHEMATIC

Pneumatic force acting on the operating piston is transferred directly to the hydraulic pressure chamber. Displacement to the opposite cylinder chamber is performed via an adjustable needle valve and a check valve. Both adjustment controls provide precision speed adjustment, independently in both directions of rotation.

Optional brake valve can be fitted to achieve a hydraulic lock for positional and emergency control
