How the Valve Operates
Input air pressure at 70 psi (4.8 bar)
forces the internal piston
➀➀
to move.
➁➁
The piston rod pulls open the
diaphragm seal,
➂➂
permitting fluid
flow. When the input air pressure is
relieved, the spring retracts the piston
and the diaphragm closes.
The primary control of deposit size is the valve open time.
ValveMate Concept
The ValveMate 7000 provides easy
adjustment of valve output for maximum
end-user convenience and efficiency.
Valve open time is the primary control of
deposit. The 7000 puts push-button
adjustment of valve open time where it
needs to be—at the valve.
Deposit size can be programmed by
pressing the PROGRAM button in the
SETUP mode. This affords an easy
starting point for selecting deposit size.

Pressure/Time Toggle
The amount of fluid dispensed will
depend on the time the valve is open,
the viscosity of the fluid, the air pressure
in the fluid reservoir, the dispensing tip
size and the diaphragm stroke.
Flow rate is a function of reservoir
pressure, tip size and fluid viscosity.

To calibrate the valve, the “0” mark on
the stroke reference ring should align
with one of the two reference marks
on the valve body. When the set-screw
is tightened, the valve is calibrated.
