Pneumatic actuator installation and debugging

Publish time: 2023-11-03 12:13:26

In mechanical operation, pneumatic actuators play a vital role, which requires everyone to understand the installation, debugging, maintenance and failure analysis of pneumatic actuators. Only the correct installation, operation and necessary maintenance, in order to make the valve maintenance work to achieve the due effect and purpose of use. 

Installation and debugging 


1.Installation of actuator and valve 

After taking the gas cylinder, first check whether the model of the gas cylinder is correct and whether the gas cylinder is open or closed. Generally, it is installed in closed state (large diameter valves can also be installed in open state). 


2. Check the direction of cylinder rotation, open the valve counterclockwise and close the valve clockwise. 


3. When connecting the cylinder with the valve, check whether the center distance of the cylinder connecting hole is consistent with the center distance of the flange connecting hole on the valve. 


4. Check whether the cylinder shaft is consistent with the valve shaft. If the shaft is not aligned, add a square sleeve. 


5. When installing, the cylinder should be in the same state as the valve (note that it cannot be opened and closed at once, otherwise the valve rotates in the opposite direction). 


6. Installation state: (except special requirements) butterfly valve and actuator are installed at 90 degrees. Ball valves are installed parallel to actuators. 


Solenoid valve installation (as required) 

1. If the solenoid valve needs to be installed after the installation of the pneumatic actuator, please pay attention to whether the O-ring on the solenoid valve is in good condition. 

2. After installation, check whether the exhaust valve is completely closed. Otherwise, remove the solenoid valve and rotate 180 degrees to reinstall it (no special requirements (completely closed after installation). 

3. Install the responder 

First remove the screw on the indicator cover at the upper end of the cylinder, insert the casing connecting shaft into the groove of
