Operation
WARNING
To reduce the risk of overpressurization which can
cause component rupture and serious injury, never
exceed 900 psi (63 bar) fluid pressure or 100 psi
(7 bar) air pressure to the dispense valve.
Starting and Adjusting the Flow
1.
Open the air (A) and fluid (B) supply lines to the
dispense valve.
2.
Trigger the dispense valve until fluid begins to flow
evenly from the needle nozzle (14) and all air is
expelled from the system. Close the valve to stop
the flow. The valve and fluid line are now primed.
See Fig. 3.
NOTE:
When using a foot valve kit (see page 12),
press the foot pedal to trigger the dispense valve, and
release the pedal to stop the flow. On Model 235877
Dispense Valve, press the trigger (G) to open the
valve, and release to stop the flow.
3.
To adjust the flow and bead size, make the follow-
ing adjustments in the order given:
a.
Adjust the fluid inlet pressure to the valve to
get the desired results.
b.
To change the bead width or shot size, or to
adjust for heavier or lighter viscosity fluids,
change to a different size needle nozzle (see
page 12 for available sizes).
c.
For finer adjustments, turn the adjustment
knob (6) to the right. To maintain the desired
setting, tighten the lock nut (8).
NOTE:
Time-pressure Controller 692018 is available
for precision dispensing of very small quantities of
fluid. See page 12 to order.
Shutdown
1.
Always follow the
Pressure Relief Procedure
on
page 5 whenever you stop dispensing, even for
only a short time.
2.
When the dispense valve is not in use, remove the
needle nozzle (14) or place a cork over the tip (see
Fig. 3).
3.
Never soak the entire dispense valve in solvent.
Disconnect the fluid section from the air section by
unscrewing the valve housing (11). Soak only the
fluid section (F).
