DESCRIPTION
A solenoid-operated, electrically-variable, two-port, pressure-compensated, spool-
type, normally closed when de-energized, proportional fl ow control valve.
OPERATION
The PV72-20 will regulate fl ow out of port ➁ regardless of system working pressure.
With an increasing current applied to the solenoid, the PV72-20 will increase output
fl o w .
Operation of Manual Override:
To Engage: Turn clockwise approximately 1 turn to reach start point. Continue
another approximately 5 turns to full shift.
To Disengage: Turn counterclockwise approximately 6 turns until positive stop
is found.
FEATURES
• Excellent linearity and hysteresis
characteristics.
• Hardened spool and cage for long life.
• Effi cient wet armature contsruction.
• Optional coil voltages and terminations.
