Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
This procedure describes how to relieve pressure from
the dispense valve. See the supply system manual for
instructions on relieving pressure from the entire sys-
tem.
1.
Shut off material supply pumps.
2.
With the valve pointed into a grounded metal pail,
use the lever (H) to open the inlet ball valves (J) and
relieve the fluid pressure.
3.
If the valve nozzle or fluid hose is clogged or if pres-
sure has not been fully relieved after following the
steps above:
a.
Use lever (H) to close dispense valve inlet ball
valves (J).
b.
VERY SLOWLY loosen the static mixer nut (G)
from the outlet manifold (F) or the hose end
coupling to relieve pressure gradually, then
loosen completely. Clear hose or nozzle
obstruction.
c.
Use lever (H) to open dispense valve inlet ball
valves (J).
Daily Shutdown
NOTE: For brief shutdowns, leave the cured mixer in
place until it is time to use a fresh mixer.
When you finish using the 2K Manual Dispense Valve,
clean the outlet manifold (F) and protect it from drying or
crystallization as follows:
1.
Perform Pressure Relief Procedure, page 10.
2.
Remove and properly dispose of the static mixer.
3.
Dispense one shot of material into a waste con-
tainer to clear any crossover in the outlet
manifold (F).
4.
Wipe the nose with a clean rag, being careful not to
let the materials contact each other.
5.
Install PTFE night capt (19) and retaining nut (G).
Flushing
Flush the valve regularly to remove material build up.
1.
Perform Pressure Relief Procedure, page 10.
2.
Remove static mixer.
3.
To maintain ground continuity, press and hold a
metal part of the dispense valve against the side of
a grounded metal pail then pump solvent through
the gun into the grounded metal pail until clean sol-
vent is dispensed. Use the lowest pressure possible
while dispensing solvent.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury
from pressurized fluid, such as skin injection,
splashing fluid and moving parts, follow the Pressure
Relief Procedure when you stop spraying and before
cleaning, checking, or servicing the equipment.
