Spring return pneumatic actuator with handwheel Benefits：

1. Modular spring pack

According to different air pressure with different spring combination, low stress spring design can effectively extend the service life of the spring.

2. Corrosion-resistant connectors

All connection bolts are stainless steel with good corrosion resistance

3.Piston ring

The piston guide ring, made of ultra high molecular polymer, has an extremely low coefficient of friction, while the material has high hardness and excellent wear resistance, providing precise guidance and long service life.

4.Body

The cylinder body is processed with high precision and anodized. The thickness of the oxide layer is more than 20μm. It has low friction coefficient and excellent anti-corrosion and wear resistance.

5.Shaft bearing

Prevent direct contact between shaft and cylinder body, ensure the positioning accuracy of drive shaft, reduce friction loss, make the actuator efficient operation.

6.Piston bearing

Ensure the positioning accuracy of the piston, so that the piston can be smooth and smooth operation, prevent shifting.

7. Pin connection

The fork and the drive shaft are connected by pins to ensure that the fork and the drive shaft run synchronously. At the same time, the pins also play a role in preventing the drive shaft from flying out, which is a reliable and safe design.

8.Handwheel

The handwheel integrated on the actuator reduces the space required for installation and reduces the load on the pipeline.
