Product Description

Corrosion resistant SR-75 Single Acting Rotary Pneumatic Actuator spring return





1. Accept continuous gas signal and output linear displacement (continuous electrical signal can also be received after the power/gas conversion device is applied), and some can output angular displacement when equipped with rocker arm.

2. It has positive and negative functions.

3. The moving speed is large, but the speed will become slower when the load increases.

4. The output force is related to the operating pressure.

5. High reliability, but the valve cannot be maintained after the gas source is interrupted (it can be maintained after adding a retaining valve).

6. It is inconvenient to realize segment control and program control.

7. Simple maintenance and good adaptability to the environment.

8. The output power is large.

9, with explosion-proof function.


► Features


Compact double-piston gear, rack-and-pinion structure, precise meshing, high efficiency, and constant output torque.
Aluminum cylinder body, piston and end cover are the lightest in weight compared to the same size and structure of the actuator.
The cylinder body is made of extruded aluminum alloy and is treated with hard anodizing, and the inner surface is hard in texture, high in strength and hardness. Sliding bearings made of low-friction materials avoid direct contact between metals, with low friction coefficient, flexible rotation and long service life.
The installation and connection dimensions of pneumatic actuators and valves are designed according to international standards ISO5211, DIN3337 and VDI/VDE3845, and can be interchanged with ordinary pneumatic actuators.
Air supply holes comply with NAMUR standards.
The shaft assembly hole at the bottom of the pneumatic actuator (in accordance with ISO5211 standard) is formed into a double square, which is convenient for linear or 45° angle installation of the valve with square stem.
The top and top holes of the output shaft are NAMUR compliant.
Adjusting screws at both ends can adjust the opening angle of the valve.
There are double-acting and single-acting (spring return) of the same specifications.
The direction of the valve can be selected according to the needs of the valve, clockwise or counterclockwise.



► Install solenoid valve, positioner (opening indication), echo device, various limit switches and manual operation devices according to user needs.
