SY Series Valves
Double solenoid, 3-position, spring centered. Spool is centered when both solenoids are de-energized. Standard models are assembled for "Internal Pilot" operation. This operator style will operate reliably on line pressures from 160 PSI down to 50 PSI. If the line pressure is 160 PSI to 250 PSI or less than 50 PSI to 28" Hg, then the solenoid operator must be configured to use an "External Pilot" source.
