LESSON 9

The Dispense Valve

OBJECTIVE:

Upon completion of this lesson, the student should be able to

describe how the dispense valve dispenses fluid.
.

THE DV-0X SERIES

VALVE ON

•

Air pressure is applied to the fluid
syringe via the receiver head.

•

The air pressure forces fluid down
the channel to the rotating auger feed
screw.

•

The DC motor turns the feed screw at
a constant speed, moving fluid
through the valve.

AIR
PRESSURE
REMOVED

The motor rotation can be reversed,
which reverses the direction of the
feedscrew, and creates a suckback effect.

AUTOMATIC
MODE

•

The speed control monitors the back
electromotive force (EMF).

•

More power is supplied to keep the
motor speed constant as fluid
viscosity changes.
