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