Tips: How to install pneumatic valve actuator?

1. After taking the cylinder, first check whether the cylinder model is correct and whether the cylinder is open or closed. Generally, it is closed during installation (large-diameter valves can also be installed in an open state)
2. Check the rotation direction of the cylinder, open the valve counterclockwise and close the valve clockwise.
3. When the cylinder is connected to the valve, check whether the center distance of the cylinder connection hole is consistent with the center distance of the flange connection hole on the valve.
4. Check whether the cylinder shaft is consistent with the valve shaft. If the shafts are inconsistent, add a square sleeve.
5. During installation, the cylinder should be in the same state as the valve (be careful not to open one and close the other, otherwise the valve will rotate in the opposite direction).
6. Installation status: (except for special requirements) the butterfly valve and the actuator are installed at 90 degrees. The ball valve is installed in parallel with the actuator.
