Typical Applications, Cont.
PRESSURE REDUCING
The pressure reducing operation prevents the output pressure from increasing above a
predetermined value. This application requires a PC Pressure Regulating Pilot Valve, or
comparable valve. Rotate the adjusting screw on top of the pilot valve counterclockwise to
increase the desired output pressure and clockwise to reduce the desired output pressure.
Connection Information
The sensor connection runs from the output connector on the hydrometer to the pilot valve
controlled input connector (1).
The pressure supply connection runs from the hydrometer input connection to the pilot valve
supply connector (3). This connection branches off to the “Close” connection on the 3-Way
Selector.
The command connection runs from solenoid to the “Auto” connector on the 3-Way Selector and
continues on to the pressure controlled input connector (2) on the pilot valve.
The vent connector (4) on the pilot valve serves as a vent.
