using the setup as pictured, I've been testing spring pressures and checking diaphragms for leaks using regulated compressed air.
stock actuators : test pressure at 20 psig, rod begins to move at about 8 psig
HD actuators : test pressure at 25 psig, rod begins to move at about 16 or so psig.
How long should the pressure hold at these levels during this bench test? 15 minutes? 30 or 60?
System pressure will gradually bleed down in any static testing. After an hour or two there could be a drop in pressure of 0.5 to 1.0 psig. The pressure drop would be much larger and faster if there was a problem.
Any insight in appreciated.
