 Product Advantages 


1. Large opening and closing torque, more suitable for butterfly valve and ball valve control

2. Longer life, smooth and wear-resistant shaft sleeve, multi-point guide seal, improve sealing performance and greatly reduce friction rub, and play the role of support and fixation, which can make the piston and the fork more flat during the movement. Stable, the service life can reach more than 1,000,000 times

3. Small size, light weight and easy installation, Due to its unique fork-type high-torque structure, under the condition of the same output torque, the

lighter than rack-type pneumatic actuators, the volume can be reduced by 30%

4. Low air consumption, energy saving and environmental protection

Compared with the rack and pinion type, the air consumption is reduced - (40%cm3/Nm), and the compression is reduced, and a smaller size compressor can be selected

5. Work faster, compared with the rack-and-pinion pneumatic actuator with the same torque, the cylinder body is smaller and the working response is faster. The transmission coordination is precise and the adjustment precision is higher. The transmission parts such as shift forks and balls have strict machining accuracy. The comprehensive transmission coordination precision is controlled below 0.1mm, which is suitable for high adjustment conditions.
