PV16-23 Valve

SYMBOL:
PV16-23 Valve symbol
DESCRIPTION
A solenoid-operated, 2-way, normally closed, proportional flow control, screw-in
hydraulic cartridge valve intended for use with an external pressure compensator
or load-sensing pump control.

OPERATION
Whe de-energized, the PV16-23 blocks flow from 1 to 2. With increasing current applied
to the solenoid, output flow from 1 to 2 will increase proportionally. The PV16-23 is intended
for use with an operating differential across the valve of 7 bar to 11 bar (100 psi to 160 psi).
The set value of the external pressure compensator or pump control must provide for both
the valve operating differential, as well as for system losses between the compensator and
the PV16-23 at the maximum required flow.

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.
• Efficient wet-armature construction.
• Optional coil voltages and terminations.
• Unitized molded coil design – 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.
