Technical Information
General Description
Pressure Compensated Priority Flow Regulator Valve.
For additional information see Technical Tips on pages
FC1-FC4.
Caution: If the priority line is blocked so that no flow
can pass through the control orifice; the compensator
spool will shift, blocking the bypass port and allowing
inlet pressure to go to full system relief pressure. The
FP101 cartridge does not provide a pressure relieving
function.
