Hydraulic control valve

[Jay4200]

No I didn't and I never was able to blow air through it like I thought it should. JJ said it would likely have to overcome some resistance or check valve to get through to the valve ports and so I assumed it would work and it did.

Thanks Gary - that makes me feel a little more confident, even if I can't get any airflow through the IN port. I have all of my gizmos together and planned on doing the final hook-up for my snowblower remote setup this weekend, but wasn't about to hook up anything before verifying that I have the right valve and spools. I'm not one for completely trusting that some counter guy will always pick the right thing off the shelf. I did get good results and was able to map the work ports using the OUT discharge port, so I could just stick with that and hope for the best.

I was thinking of putting together a little adapter so I can plug my air compressor into the IN port - think 100PSI would be enough to defeat whatever is in there? I'd just been blowing through the ports with my mouth.

I have no idea how much pressure it would take but if you find out, let me know please. Not that it makes any difference but just curious. If you do want to test it, start with about 20lbs and work your way up till it opens. Appears to be associated with valves that have a check valve to prevent the loader from moving when the lever is in the neutral position. I put a full load of dirt in my bucket last night and raised it half way up to see if it had dropped any by the next morning. Nope, still where I left it so I guess it's working the way it should. It's always nice if you can put some pic's up when it is completed so everyone can see how it comes out.

Just to give you a reference on how much air pressure you can make with your mouth. (not talking about me!!:laughing
If you have acces to a swimming pool, stick a tube of some sort in the water and try blowing in it and watching your depth.(blowing bubbles ) You would probably be lucky, or have good lungs if you can get to 4' depth. At .433 psi water column, that would be roughly 1 3/4 psi.
Any valve that has checks, has a breaking pressure of probably close to 5 psi. That is just WAG on breaking pressure.

Should've plugged it into the other end. I could definitely generate 5PSI that way (or so my wife would claim...)
