Is there anyone here who has some experience with sub-base mounted
pneumatic valves?

The valve that controls the speed adjustment motor is not working
quite right.

I know the follownig.

1. It is a sub-base mounted valve with 5 ports.
2. It has two soleniods.
3. When air is applied directly to the speed control motor, without
the valve, the motor works great.
4. When I use the soleniod valve to control the motor, it hisses a lot
and i barely moving the motor (compared to previous test).
5. I took the valve apart and did not find anything obviously wrong:

I have a feeling that I simply did not find what was wrong with the
valve.

My first question is, does it look like a standard sub-base valve?
What are the standards? Can it be replaced with something off the
shelf?

My second question, is how would I go about diagnosing why exactly
does this not seem to work right.

Check the exhaust ports. If they have those sintered metal mufflers,
they may be plugged.

Haven't seen it as I am on dial-up and your pictures are usually quite
large. But have you considered using any 4-way valve? Just have to
plumb it in and wire it up.

Yep, if I fail at this one, I will just get another valve.

Ah! Yes indeed! A common enough problem in commercial machine shops.

I didnt think of this, because most machine shops now days use either
screw compressors and dryers, or dryers alone..and you dont have a
dryer, do you?

Pick one up at an auction. Doesnt need to be a big one. One the size of
a bread box will do you just fine. Get a 110vt one.

If they still have it, the Harbor Freight refrigerated air dryer is an
exceptionally good deal.

I do have an air dryer that I bought for $10. It is rated for 15
CFM. My mill right now is plumbed through it (though sometimes I
forget to turn it on).

It should be on the same circuit as your compressor. Seriously. If the
compressor is hot..the dryer should be running

I got one for the air at the plant. Had it for 2+ years. Beware, the
automatic water dump has never worked on ours and we clear it manually
every morning. Except for that, works well. Froze up a few times when
we didn't clear the tank soon enough.

Be sure to plumb it with air bypass capability and pipe unions for
easy removal and repair.
