PV72-30 Proportional Flow Control Cartridge,

DESCRIPTION

A solenoid-operated, electrically-variable, three-port, pressure-compensated, spool-

type, normally closed when de-energized, proportional ﬂ ow control valve. It can be

used as a priority-type ﬂ ow regulator with pressure-compensated, regulated and

bypass ﬂ ow. It can also be used as a restrictive-type 2-way, pressure-compensated

ﬂ ow regulator when the bypass line (port

➁) is blocked.

OPERATION

The PV72-30 will regulate ﬂ ow out of port ➂ regardless of system working pressure.

With increasing current applied to the solenoid, the PV72-30 will increase output ﬂ ow.

Note: When used as a bypass ﬂ ow control in applications where the priority ﬂ ow port

will be blocked by external valving, bypass pressure drop will increase unless a small

amount of leakage is provided for the priority port. Consult factory.

Operation of 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 to positive stop.

FEATURES

• Excellent linearity and hysteresis .

• Hardened spool and cage for long life.

• Efﬁ cient wet armature construction.

• Optional coil voltages and terminations.
