Pneumatic Regulators from Automation Direct

It might be good to point out to the Q&A people that the recommended regulator can be adjusted to above 60 PSI.

Ya, the original question was quite a bit longer and pointed out all the important details touched on in this thread. There is a character limit on q and a's that made adding more details impossible though.

I could have linked this thread, but I suspect the deciding parties are already aware of whats been stated here.

Yeah I've been trying to get them to remove or at least liberally increase the character limit for a couple years. I think they made it a bit larger last year but still not good enough. VEX Q&A forum is still better at this, they can post photos and things to help communicate their questions.

Q & A has spoken with much appreciated clarity.

Q. Is the intent of R77I to limit teams to only using Pressure regulators with a published operating range of less than 60 PSI, or is this meant to allow regulators with an operating range above 60 PSI provided they are adjusted such that the working pressure is at or below 60PSI?

A. The meaning of R77-I was unclear, sorry about that. It will be revised in Team Update 14 to allow pressure regulators with the outlet pressure adjusted to 60 psi or less. Regulators with an operating range above 60 psi will be allowed provided they are adjusted to no more than 60 psi.

And that just made inspecting pneumatic systems a lot easier than it was looking over the past week!

Indeed. This was a smart answer fueled by common sense on the part of the GDC. Definitely helpful to teams and volunteers alike.

[Paul Copioli]

Once again the GDC under Frank Merrick's leadership is the most professional and most reasonable during all my years of participating in FRC.

The practical and team centric approach that FRC has been taking during the "Frank Era" of FRC is very much appreciated.

What a courteous and professional response.

Are there any other 'less used but legal' pneumatics components that Automation Direct sells? We have a ton of old dials, regulators, brass fittings, etc. and I'd like to know some of the parts you guys have found to be better for FRC applications. Thanks for posting this to the Q&A!

100% agreed. Thanks also to all of the professional comments in this thread which helped to provide well-reasoned technical insight. This is a great update which benefits teams, RI's and LRI's. Now we can go back to worrying about more exciting things like bumpers and bagging two "robots."

Great news! We used the setup below for our robot last year and really liked it compared to massive regulators involving brass and large gauges.

Inline regulators and gauges could be useful if you need weight or space.

Quick exhaust valves are legal for the first time this year.

3 Way exhaust valves are also legal this year for closing off sections of pneumatics

Not from automation direct but McMaster and other sources carry tiny gauges (paintball sized) that are lighter. You can also get aluminum and plastic manifolds as well.

We have both these products on our competition robot and are excited to compete with them next week!

Thanks FIRST for the common sense ruling on this matter!

If using these, just remember that you still must meet R89:

A. connected to the pneumatic circuit such that, when manually operated, it will vent to the atmosphere to relieve all stored pressure in a reasonable amount of time, and

B. placed on the ROBOT so that it is visible and easily accessible.

If the compressor is not used on the ROBOT, then an additional pressure vent plug must be connected to the high-pressure portion of the pneumatic circuit off-board the ROBOT with the
compressor (see R80).

Does anyone have an example of a useful application for the 3-way exhaust valve?

A quick exhaust valve is not covered by that rule, because it is not a pressure vent plug. A quick exhaust valve is a three port valve that passe air from one port to another port in one direction, but to an exhaust port in the other direction.

[Nate Laverdure]

The inline pressure regulators linked in this thread are super cool.

The literature says that they contain "a built-in relief valve to exhaust over-pressure." What determines the relief set pressure? Is it a function of the set pressure of the regulator, or is it constant?

Genuinely interested (not trying for a gotcha!) in understanding how this device meets the intent of R82.
