The Double Acting Pneumatic Actuator is a rotary actuator driven by compressed air, commonly used to control the opening and closing of valves. It consists of a cylinder, a gear rack, a double piston system, seals, etc., which can efficiently convert air pressure signals and is suitable for automated valve control and other rotary motion applications.
feature
Fast drive response
The double piston drive structure and full lubrication design enable the Double Acting Pneumatic Actuator to maintain fast response during frequent operations, with a response time of less than 1 second, which is suitable for high-beat production lines.
Strong environmental adaptability
The Double Acting Pneumatic Actuator is made of anodized aluminum alloy material, which has excellent corrosion resistance and can operate stably in an environment of -20°C to +80°C, suitable for harsh working conditions.
Precise adjustment
The Double Acting Pneumatic Actuator is equipped with a two-way adjustable limit bolt, and the rotation angle can be adjusted from +5° to 5°, accurately matching the stroke requirements of different valves.
Bidirectional power drive
The Double Acting Pneumatic Actuator drives the cylinder in two directions through two air sources, ensuring the smoothness and control accuracy of the actuator during rotation. Within the standard pressure range of 2.5 bar to 8 bar, the actuator can provide a maximum torque of 7800 Nm.

Operation
|
Air to Port A forces the pistons outward, causing the pinion to turn counterclockwise while the air is being exhausted from Port B. |
Air to Port B forces the pistons inwards, causing the pinion to turn clockwise while the air is being exhausted from Port A. |

The above is the transmission principle of the standard type. According to the user's needs, the pneumatic actuator can be installed in the opposite transmission principle of the standard type, that is, the quasi-axis rotates in the clockwise direction to open the valve, and the counterclockwise direction to turn the closing valve.
