How the Radial Spinner System Operates
ValveMate Controller Concept
The ValveMate 7160RA radial
system controller provides
easy adjustment of valve
output for maximum end-user
convenience and efficiency.
Valve open time is the primary
control of deposit size. The
7160RA puts push-button
adjustment of valve open-time
where it needs to be — at
the valve and radial spinner
assembly.
Upon initiation of the 7160RA radial
system controller
ò
, air pressure
is released to the air motor
assembly
ù
to begin spinning
the radial disc assembly
ä
.
Immediately following, a timed
pulse of actuating air is released
to the dispense valve
ë
to apply
fluid onto the spinning disc. The
spinning disc causes the radial
output to sweep around to apply
an even band of fluid to the inner
circumference of the cylinder
ö
.
When the timed actuating air from
the 7160RA controller shuts off, the
dispense valve closes, stopping
fluid flow. An adjustable delay
after the dispense cycle ensures
that all fluid is dispersed after the
valve closes, ensuring coating
consistency from cycle to cycle.
Refer to the ValveMate 7160RA
controller operating manual
for instructions on increasing /
decreasing the delay feature.
The controller incorporates
unique microprocessor circuitry
to provide exact time control
and interaction with the host
computer.
An initial deposit size can be
rapidly programmed by using
the 7160RA TEACH mode.
Refinements can be made by
using the time setup controls.
