PV08-30 Valve

PV08-30 Valve symbol
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.

The PV08-30 will regulate flow out of port 3 regardless of system working pressure.
With an increasing current applied to the solenoid, output flow will increase.
Note: When used as a bypass flow control in applications where the priority flow port will
be blocked by external valving (dead-headed), a small bleed orifice is required at the priority
port (port 3). Consult factory.

• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.

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.
