DESCRIPTION
A linear solenoid-driven, two-way normally closed, screw-in cartridge valve designed
for use with a pressure compensator to function as an electrically stroked variable
flow regulator.
OPERATION
With increasing electric current, the PV72-33 changes from full closed to full open
with flow from port 3 to port 2. Port 1 is used only to pressure balance the spool and
should be plugged. The proportional valve is intended to function in tandem with
standard HydraForce pressure compensators at pressure differentials of 12 bar
(175 psid) or less, or alone in variable volume pressure-compensated circuits with
load sense capability.
The valve is designed to work with industry-common controllers which typically
feature current capability to 2 amps @ 12 VDC, PWM, and start/stop trim adjustments
(I-min./I-max.). Consult factory for details and potential sourcing.
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 to positive stop.
FEATURES
• Excellent linearity and hysteresis.
• Optional control orifice sizes.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet armature construction.
