PV76-30A Valve

SYMBOL:

PV76-30A Valve symbol
DESCRIPTION
A solenoid-operated, pressure-compensated, spool-type, normally closed proportional
flow control valve.

OPERATION
The PV76-30A 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 bypass line (port 2) is blocked. 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, bypass pressure drop will increase unless a small amount of leakage
is provided for the priority port.
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 coil voltages and terminations.
• Efficient wet-armature construction.
• 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.
For other Electronic Controllers, see page 2.001.1_pdf
