DESCRIPTION

A solenoid-operated, two-way, normally closed, electro-proportional, hydraulic

cartridge valve intended for use with an external pressure compensator or

load-sensing-style pump control.

OPERATION

When de-energized, the PV16-23 blocks ﬂ ow from ➀ to ➁. With increasing current

applied to the solenoid, output ﬂ ow from

➀ to ➁ 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 ﬂ ow.

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 characteristics.

• Hardened spool and cage for long life.

• Optional coil voltages and terminations.

• Efﬁ cient wet armature construction.
