fengda airbrush question?

Usually about 25 % of maximum tank pressure Andy….and that itself is usually a very conservative value
Don’t panic, just pull the power and you’ll be fine……the overpressure relief valve (ORV, safety valve) is supposed to be sized to bleed enough air out to prevent overpressurisation from attached kit like compressors. The higher the overpressurisation the wider it opens and the more air it lets out.

I hope I haven't disturbed the pressure by trying to pull it out then Tim, I did manage to just move it a tad, but not much though :anguished:

My pressure switch failed and my tank ran overnight once, I'm guessing it blew off at some point, or that there's enough leaks to keep it safe........either way nothing burst.

No worries mate. If you wound it down a tad it will just go slightly early…..if you wound it up it will go a little later, but not enough to worry about. You’d have to seriously wind it up (several turns I should think) to materially change the values.

Thanks again for all the advice guys :thumb2:

Just pulling it out won't do any damage. Some people recommend doing that occasionally to make sure the safety valve isn't stuck.

Crickey, this kit must be flying off the shelf.
It's gone up in price already, not by much though.
