ABSTRACT:
The blanketing valve has a diagnostic port to aid in analyzing the valve's operation. A pressure gauge is connectable or permanently connected to the diagnostic port. The diagnostic port measures the pressure above a main valve in a passageway connecting a pilot inlet chamber and a main valve piston chamber. This pressure controls the main valve and is an indicator of pilot valve action. Comparing this pressure to inlet pressure indicates pilot response and is a valuable aid in determining what problems may exist.
