Operation
Refer to assembly drawing
112-1352
for part reference numbers.
1)
Plumb up the valve as outlined above in the
Setup
procedures.
2)
Regulate the air pressure operating the valve between 60-100psi.
3)
Making sure that the valve is not aimed toward anyone, cycle the valve several
times. When the valve is cycling, both pistons can be heard hitting the stroke
adjustment bolts, and the needles (3) can be seen going up and down in the center
simultaneously.
Note: If the valve is not cycling properly, refer to the
Troubleshooting
section.
4)
When the fluid delivery system is connected to the valve, pressurize the fluids to
be dispensed.
5)
Once again, cycle the valve open to purge. Part A and B should begin to flow
separately out of the fluid manifold (1), continue dispensing until air is removed.
6)
Check fluid connection and packing nuts (6) for leaks. If the valve is leaking,
refer to the
Troubleshooting
section.
7)
Turn the stroke adjustment bolts (19) until the desired flow rate is achieved from
each fluid. Turning the adjustments clockwise will decrease the material flow rate
and counter-clockwise will increase the material flow rates. If the stroke
adjustment bolts are turned all the way down it will stop the flow of fluid entirely.
8)
Once the stroke adjustment settings are determined, use the adjustable wrench to
tighten the lock nuts (20) up against the upper air bodies (11).
9)
Attach a static mixer to the manifold (1) and use the retaining nut (23) to lock it in
place tightening with an adjustable wrench
Note: Refer to
Troubleshooting
section for any problems.
