    The solenoid located under the 3rd unit on the operator side are leaking out the back through the brass screen. Tried swapping them out to no avail. Need to find the cause but don't know where to start. Any help would be greatly appreciated...

    As Ashok mentioned, you must replace the piston (rams) that the valve supplies, such as the ductor on/off, dampening on/off, etc...On on pneumatic "circuits" with two rams in line, like dampening on/off, squeeze the air line at each to see if the leak stops in order to determine which ram must be replaced.

    Thank you all for your input. Problem solved. First we did find a small leak in the Festo line and replaced that. Second determined there was a faulty ram and replaced it. I really appreciate everyone for the quick responses.
