PV42-M30 Valve
U.S. Patent 6,966,329

PV42-M30 Valve symbol
A solenoid-operated, electrically-variable, 2-stage, 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.

The PV42-M30 will regulate flow out of port 3 regardless of system working pressure
at 3 or at bypass port 2. Two priority flow ranges are provided for better resolution:
Range A for priority flow up to 170 lpm/45 gpm, and Range B for priority flow up to
132 lpm/35 gpm. For either range, the input flow at 1 can be up to 225 lpm/60 gpm.
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 3 turns to reach start point.
Continue another approximately 2 more turns to full shift.
To Disengage: Turn counterclockwise approximately 5 turns to positive stop.

• Choice of two regulated flow ranges.
• Excellent linearity and hysteresis characteristics.
• Hardened spool and cage for long life.
• Optional coil voltages and terminations.
• Efficient wet-armature construction.
• Manual Override option.

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.
