Why didn't the nitrogen pressure relief valve vent for a while?

There may be a problem. Precision pressure reducing valve is used to reduce the pressure of air source and make it stable at a fixed value, so that the regulating valve can obtain stable air source power for adjustment and control. The main reason for this problem.

1, installed backwards.

2. The plastic dust plug was not unplugged during installation.

There is no reading on the watch. It may be that the solenoid valve or controller is not energized.
