Pump won't output sufficiently low pressure. Always starts at 3bars, appears to vent remaining pressure at under 1 bar.

Valve definitely leaks at those high pressures, though not insanely much.
|
|
|
|
At lower pressures of around 1.5bar it starts to seal. Review recordings!

Tube appears undamaged.

Servo is making a lot of noise at open position. Maybe the potentiometer is a bit fucked there? Something weird is definitely happening.
|
|
|
|
I also think the servo crank might not be perfectly clocked.
|
|
I think a little further forwards would be good. Might just be failure to assemble correctly, since I didn't have a reference of orientation.

I'll look for another pump now.

Second pump aquired. Eriks airbrush compressor has a regulator behind the output, and with a bunch of adaptering I can couple that into the valve.
|
|
However, the valve did aparently just hold 2.something bar without any visible leaks for well over a minute.

I think that is testing for today. Seems good enough to deliver, but I would like to remodel, reprint and retest. |
