DESCRIPTION
A solenoid-operated, electrically-variable, 3-port, normally closed, pressure-compensated,
proportional flow control, spool-type, screw-in hydraulic cartridge valve. It can be used as
a priority-type flow regulator with pressure-compensated, regulated and bypass flow. It can
also be used as a restrictive-type 2-way, pressure-compensated flow regulator when the
bypass line (port 2) is blocked.

OPERATION
The PV72-30 provides priority-regulated flow at port 3 with pressure-compensated regulated and
bypass flow. The regulated flow is proportional to electric current applied to the solenoid.
Note: When used as a bypass flow control in applications where the priority flow port will be
blocked by external valving (dead-headed), bypass pressure drop will increase unless a small
amount of leakage is provided for the priority port. Consult factory.

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
• Choice of two regulated flow ranges
• Excellent linearity and hysteresis characteristics.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Cartridges are voltage-interchangeable.
• Unitized, molded coil design.
• Coil waterproofing standard.
• Manual Override option.

RECOMMENDED ELECTRONIC CONTROLLERS
The EVDR Series controllers are recommended for use with most HydraForce
proportional valves. These newer electronic controllers are versatile, reliable,
and easily configured and customized for a wide range of applications.
See the EVDR Product Selection Guide.
