How the Valve Operates
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 start-
ing point for selecting deposit size.
Note: The EFD Ultra TT 325 and 525
XYZ automated dispensing systems have
integrated ValveMate controllers for oper-
ating all EFD dispense valves.

➀➀
Input air pressure at 70 psi (4.8 bar) retracts
the piston and needle from the needle seat
in the dispensing tip
➀➀
, permitting fluid flow
through the dispensing tip
➁➁
. Once the
cycle is complete, air pressure is exhausted,
causing the piston spring
➂➂
to return the
needle back to its position in the dispensing
tip, stopping fluid flow. When the dispensing
tip is removed, the needle seats into a sec-
ondary Teflon

seat
➃➃
, stopping fluid flow
during tip replacement.
The amount of fluid dispensed
will depend on the time the valve
is open, fluid reservoir pressure,
dispensing tip size, needle stroke
and fluid viscosity.
