How the Valve Operates
ValveMate Concept
The ValveMate 7090 provides
easy adjustment of valve output
for maximum end-user conven-
ience and efficiency. Valve open-
time is the primary control of
deposit. The 7090 puts push-
button adjustment of valve open-
time where it needs to be – at
the valve.

Microprocessor circuitry provides
exact control of the spray valve
to achieve exceptional spray pat-
tern definition. The ValveMate
7090 also incorporates micro-
processor-controlled functions
that include motor start-up

Duration of the dispensing time
is controlled by adjusting the
time control up or down until the
required deposit size is estab-

with each initiate cycle.
