How it Works
nu
Open
Relief unit, set at maximum gauge pressure, is closed. Check valve unit is open, allowing System pressure to pass into gauge.
Closing
When maximum pressure of gauge is reached, relief valve opens, preventing any further pressure increase. Check valve immediately closes.
Closed
Check valve isolâtes gauge from System. Relief valve closes, trapping pressure in gauge. Check valve reopens when systerr pressure is reduced.
