A solenoid operated, electrically-variable, two-port, pressure-compensated, spool-type, normally open when de-energized, proportional flow control valve.
The PV72-21 will regulate flow out of port ➁ regardless of system working pressure. With an increasing current applied to the solenoid, the PV72-21 will decrease output
flow.
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.
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Effi cient wet armature construction.
• Optional coil voltages and terminations.
Operating Pressure: Port ➀: 240 bar (3500 psi); Port ➁: 207 bar (3000 psi)
