Team Update #11

[Gary Dillard]

Here's how I plan to do it:

We'll pressurize the system to cutoff with the pressure switch (around 115-120 psi), then back off the jam nut and turn the valve until it relieves. We'll go back the other way a little (1/4 turn?), jumper across the pressure switch, and watch the gauge to see where it relieves. We'll iterate from there.

... We used this method and it worked OK. You could hear the valve venting and see the pressure slow down at ~125, it went up to ~135 or less and held there until we released the pressure switch jumper; then it vented back to ~125 and stayed there. With the hysteresis on the valve I think that's about the best you can expect.
