Assured Automation- We Make Automation Easy
In this video we will be converting an E Series Fail Closed pneumatic actuator to Fail Open.
First remove the indicator cap from the top of the actuator
Please note that the slot in the shaft is perpendicular to the actuator housing. Next remove spring end caps
To remove the internal pistons, place a wrench on the actuator stem and rotate counterclockwise until the pistons can be pulled out. It is very important to Note the orientation of the pistons as they come out of the actuators, since you will rotate them 180°
Rotate the pistons 180 degrees, Push them into the actuator to engage with the pinion
Rotate the shaft counterclockwise until the pistons are pulled fully into the actuator housing. Note the slot on the shaft should now be parallel to the actuator housing
Reattach and tighten the spring end caps
Attach indicator cap
The actuator should rotate clockwise when air is applied. It should spring closed counter clockwise when air is removed.
