AT series pneumatic actuator

PRODUCT OVERVIEW

At series pneumatic actuator is a double piston rack and pinion rotating structure design, which is divided into double action and single action (spring return). Through the innovative and optimized design of CAD three-dimensional model, the shape is beautiful, compact and modern; The utility model material and new technology are adopted to make the quality and performance of the product more reliable; Multi specification selection is more economical; The products fully comply with international standards and technical specifications to meet current and future needs.

PRODUCT FEATURES

1. The extruded aluminum alloy cylinder block has a hard surface texture and strong wear resistance after hard oxidation treatment.

2. Compact double piston gear and rack structure, accurate meshing, stable transmission, symmetrical installation position and constant output torque.

3. F4 guide rings are installed at the moving parts of piston, rack and output shaft to achieve low friction, long service life and avoid metal contact.

4. The cylinder block, end cover, output shaft, spring and fasteners are subject to anti-corrosion treatment.

5. The spring of single pneumatic actuator is installed after preloading, which can be safely and conveniently disassembled and assembled.

6. The two-way stroke adjustment of 0 ° and 90 ° plus or minus 5 ° can be carried out in the fully open and fully closed positions.

7. The installation and connection dimensions comply with ISO5211, din3337, VD1 / vde3845 and numar standards to ensure interchangeability between and facilitate the installation of solenoid valves, limit switches and other accessories.

8. The mounting and connecting holes of the output shaft have a variety of shapes (square hole, shaft key hole and flat hole).

9. It has beautiful and exquisite appearance, light weight and waterproof sealing structure.

10. There are normal temperature type, high temperature type and low temperature type. Nitrile rubber shall be used under normal temperature working conditions, and fluororubber or silicone rubber shall be used at high or low temperature.

WORKING PRINCIPLE (ATD)

CCW：

Inlet A. compressed air overcomes the spring force. Push the piston outward, turn the actuator output shaft counterclockwise (0 ° → 90 °), and exhaust at port B;

The actuator loses air, the piston moves inward under the action of spring force, the output shaft of the actuator rotates clockwise (90 ° → 0 °), and the air is exhausted at Port A.

CW：

Inlet a, compressed air overcomes the spring force, pushes the piston outward, the actuator output shaft rotates clockwise (0 ° → 90 °), and outlet B exhausts;

The actuator loses air. The piston moves inward under the action of spring force. The output shaft of the actuator rotates counterclockwise (90 ° → 0 °) and vents at Port A.

OPERATING PRINCIPLE (ATE)

CCW：

Intake air from port a, the compressed air pushes the piston outward to rotate the actuator output shaft counterclockwise (0 ° → 90 °), and exhaust air from port B.

Intake air from port B, the compressed air pushes the piston inward to rotate the actuator output shaft clockwise (90 ° → 0 °), and exhaust air from Port A.

CW：

Intake air from port a, the compressed air pushes the piston outward to rotate the actuator output shaft clockwise (0 ° → 90 °), and exhaust air from port B.

Inlet port B, compressed air pushes the piston inward to rotate the actuator output shaft counterclockwise (90 ° → 0 °), and exhaust port a.
