Single acting pneumatic actuator

Introduction

Rack and Pinion Type Single acting Pneumatic Actuator uses the purified air to drive the shaft of valves thus the shut-off and control regulation of piping system can be realized. It features in spring loaded mechanism and compact construction with reliable longevity and security.

Working principle

When the pressure of the air source enters the middle chamber between the two pistons of the cylinder from the air port ‘’2’’, the two pistons are separated and moved toward the ends of the cylinder, forcing the springs at both ends to compress. The air in the air chambers at both ends is discharged through the air port ‘’4’’. The two piston racks synchronously drive the output shaft to rotate counterclockwise.

After the air source pressure is reversed by the solenoid valve, the two pistons of the cylinder move in the middle direction under the elastic force of the spring. The air in the middle chamber is discharged from the air port ‘’2’’, and the two piston racks simultaneously drive the output shaft to rotate clockwise.

If the piston is installed in the opposite direction, the output shaft will turn in reverse when the spring returns.

Feature:

1. Rack and pinion configuration, easy installation, convenient maintenance;

2. Aluminum shell with anodizing surface provides corrosion proof performance;

3. All internal metal parts are coated with high peformance lubricants to maximize the applicable temperature scope;

4. Two positioning bolts to allow the adjustment of ±5° when fully closed and fully opening

5. All pneumatic accessories conform to VDI/VDE 3845 and NAMUR standards and ISO mounting according to ISO5211 and DIN3337 (F03-F25)

6. Preloaded coating springs are made from the high quality material for resistant to corrosion and longer cycle life, which can be demounted safely and conveniently to satisfy different requirements of torque by changing quantity of springs
