How the Valve Operates
ValveMate Concept
The ValveMate 7060RA provides
easy adjustment of valve output
for maximum end-user conven-
ience and efficiency. Valve open-
time is the primary control of
deposit size. The 7060RA puts
push-button adjustment of valve
open time where it needs to be –
at the valve.
The controller incorporates
unique microprocessor circuitry
to provide exact time control and
interact with the host computer.
A built-in air pressure regulator
provides low volume low pres-
sure nozzle air to ensure high

across the fluid nozzle at a 70° angle.
This atomizing air creates a pressure
drop around the nozzle, causing fluid
to atomize into fine droplets and follow
the direction of the atomizing air flow.
The rotor, spinning at approximately
2500 rpm, causes the radial output to
sweep around and evenly coat the
inner circumference of the cylinder.
When the timed actuating air
from the ValveMate 7060RA
controller shuts off, the piston
spring moves the needle onto
the nozzle seat and shuts-off
fluid flow. An adjustable
atomizing air delay ensures
that all fluid is atomized after
the valve closes, eliminating
post-deposit spatter.

Deposit size can be pro-
grammed by pressing the
PROGRAM button in the
SETUP mode. This affords
an easy starting point for
selecting deposit size.
