How the Valve Operates
Input air pressure at 70 psi (4.8 bar) forces the internal
piston to move.
The piston rod pulls open the diaphragm seal, permitting
fluid flow. When the input air pressure is relieved, the spring
retracts the piston and the diaphragm closes.
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.
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 – near 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.
