Compressor Pressure Switch Adjustment

If the pressure range of a fixed range pressure switch was 45 PSI, for example, and the normal cut in pressure was 90 PSI, then turning the adjustment screw clockwise may change the cut in pressure to 95 PSI. The cut out pressure would automatically become 140 PSI, or 45 PSI higher.

How do I know how much pilot pressure is required to …

Two areas work to open a counterbalance valve—the relief area and the pilot area. The pilot area divided by the relief area equals the pilot ratio. Reverse flow from port 1 to port 2 is blocked by the check valve until a pilot pressure is sensed at port 3 (pilot) that is inversely proportional to the load pressure at port 1 (load).).
