KSB Germany DYNACTAIR ECO12 F05 DD14 Pneumatic Actuator is a double-piston rack and pinion rotating pneumatic actuator. KSB's pneumatic actuators are piston-type with long piston strokes, suitable for applications requiring high thrust. They can directly drive valve stems and can also be used in combination with worm gears.

Interface Standards
The interface between the actuator and valve complies with ISO5211 and DIN3337.
The interface between the actuator and control valve (solenoid valve, etc.) complies with NAMUR.
The interface between the actuator and signal unit (limit switch, positioner) complies with NAMUR.
Stroke Range and Open-Close Angle Adjustment
Standard stroke: 0°±5° to 90°±5° (Two independent external adjustment bolts allow for a ±5° adjustment range at both 0° and 90° simultaneously.)

The KSB Germany DYNACTAIR ECO12 F05 DD14 Pneumatic Actuator features a symmetrical double-piston rack and pinion design, ensuring fast and smooth operation, high precision, and high output power. Reverse rotation can be achieved by simply changing the piston assembly position.
The KSB Germany DYNACTAIR ECO12 F05 DD14 Pneumatic Actuator uses compressed air as the power source, converting the linear motion of the piston rack into the rotational motion of the output shaft via gear transmission. It is available in double-acting and single-acting types and is widely used for the switching and regulation of quarter-turn valves such as ball valves, butterfly valves, and plug valves. It is also suitable for other rotary applications, making it an ideal device for industrial pipeline automation control.
