HAAS Fix Tool Release Issues due to defective Humphrey valve clogging the air lines | TM-1 Mini-Mill

This video shows an easy fix to tool release issues for a HAAS TM-1 and similar models like the HAAS Mini Mill. The problem in this case is clogged air lines and a defective Humphrey valve SQE2 (Super Quick Exhaust valve).
The Humphrey valve has a rubber valve inside that is designed to allow air to only flow in one way and out the exhaust. In this situation, it is being used slightly differently, where low pressure air enters on one side, high pressure air enters the exhaust, and then all the air is released out the exhaust. The rubber valve inside that controls the air flow direction has turned into goo, and pushed out the low pressure airline, clogging some of the low pressure components.
The easy fix is to clean the goo out of the airlines and fittings, and replace the Humphrey valve with the same SQE2 valve. However, I've seen people complaining about Humphrey valve failing in 5-10 years. I want something more durable, so instead of buying a Humphrey brand valve, which I know will fail the same way in 5-10 years, I bought this Parker/Legris valve which I hope will last longer amzn.to/3fXwRpT

These videos you are doing are amazing. I got a 2006 TM1 recently and it had exactly the same issue! They must fail after a certain amount of time. Also working on building a tool changer for mine and your videos are extremely helpful with that! I was also told by my HFO that they would not sell me any parts for it.

Thanks, trying to document this stuff to help each other. Instead of buying a Humphrey brand valve, which I know will fail the same way in 5-10 years, I bought this Parker/Legris valve which I hope will last longer amzn.to/3fXwRpT

@@engineerable looks like they're getting two orders today 🤣

@@evancooper1195 I replaced it with the Legris valve, and it works. Here's the video ruclips.net/video/UPQi0CrQKTY/видео.html
Hope it lasts longer than the Humphrey valve.

Sucks that the humphrey valve is getting replaced. I work there on the cnc side of things. If the competition works better, i can't argue.

Went ahead and ordered this from amazon. I'll fix it when I break in and fix those motor bushings. Again, Thanks a lot for your help.
