NOTE:
In general, the flow area ratio of the orifice
valves should be equal to the material ratio, but it will
also be influenced by differences between "A" and "B"
material viscosities and flow characteristics. For flow
-
able materials, start with a smaller orifice combination
to increase pressure. For heavy viscosity, paste materi
-
als, start with a larger orifice combination. It is desirable
for the orifice to do the majority of the pressure adjust
-
ment, as this will result in the most stable system.
Adjustments of the needle valve (if used) will require
periodic adjustment.
* Item included in kit 24E250
NOTICE
Not properly maintaining the pressure differential
between inlet and dispense pressures may cause
inconsistent pump output. Adjust the needle valves
periodically to maintain pressures.
