I used to work on pneumatic equipment all the time. It can be a common problem.
99% of the time at he valve outlet there is a sort of "Filter" usually a sintered brass filter much like the old Fuel filter that fit in the inlet of a carb fuel fitting.
Anyways these filters are there to keep bugs from making nest in the open pipe hole of the valve and some times they get dirty on the inside for the lube oil that gets there from the air/ and air compressor.
look at that filters and if they are dirty.

You will have to just get under there when they are being lowered to find where the air lets out.
BE CAREFUL.
