How the QR Clasp Works
The QR clasp slides into grooves to wedge the fluid
body against the air cylinder body. A thumbscrew
secures the entire valve assembly to prevent movement
during cycling. The thumbscrew also acts like a jack
screw to ease QR clasp removal.

How to Control the 781Mini Valve
Two controllers are recommended for use with the 781Mini
spray valve: the ValveMate
™
8040 and the ValveMate
™
7140.
For multiple valve installations,
use the ValveMate 8040
controller to provide easy adjustment of valve output
for maximum end-user convenience and efficiency. The
ValveMate 8040 controller puts push-button adjustment of
valve open time where it needs to be — at the valve.
The ValveMate 8040 features micro-processor circuitry for
extremely precise control of deposit size. Feed lines can
be purged, initial deposit sizes set, and adjustments made
quickly and easily at the dispensing station, without stopping
the production line.
For single valve installations,
use the ValveMate 7140
controller. Incorporating programmable dispense time, digital
time readout, keypad programming for easy user interface,
and input / output communication with host machine PLCs,
the ValveMate 7140 has been designed with the machine
builder and operator in mind. The objectives are to bring
dispensing control close to the point of application and to
provide the features necessary to make setup and operation
as easy and precise as possible.
