Hydraforce PV72-33A PV7233A Spool-Type 2-Way Normally Closed - New No Box

PN: PV72-33A
PV7233A

A solenoid-operated, 2-way, normally closed, proportional 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. This valve is intended to function in tandem with standard HydraForce pressure compensators at pressure differentials of 12 bar (175 psi) or less, or alone in variable volume pressure-compensated circuits with load sense capability.

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.
⢠Optional control orifice sizes.
⢠Optional coil voltages and terminations.
⢠Efficient wet-armature construction.
⢠Cartridges are voltage-interchangeable.
⢠Unitized, molded coil design.
⢠Coil waterproofing standard.
⢠Manual Override option.
