Converting an O Series Pneumatic Actuator from Fail Closed to Fail Open

Assured Automation- We Make Automation Easy Conversion of the O Series Pneumatic Actuator from Fail Closed to Fail Open In this video we will be converting an O 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 tho the actuator housing . Remove spring end caps. This is the actuator with the end caps fully removed. 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° Here is a side view showing how the piston was removed and how it engaged the internal yoke. The bar on the piston (A) engages with the notch in the yoke(B). The shaft needs to be rotated so the piston engages on the opposite side. Use a wrench to rotate the shaft counterclockwise approximately 90 degrees. After the pistons are rotated 180 degrees , push them into the actuator to engage with the yoke. 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. Re-attach the spring end caps but be sure to match the tabbed o-ring to mate with the air port on the actuator housing Tighten end caps. Attach indicator cap The actuator should rotate clockwise when air is applied. It should spring closed counter clockwise when air is removed.
