Operation
Refer to assembly drawing
112-2928
for part reference numbers.
1)
Plumb up the valve as outlined above in the
Setup
procedures.
2)
Being sure the valve is not aimed toward anyone, pressurize the fluid delivery
system. Note: The fluid pressure must be set to a minimum of 15psi. to flex the
diaphragm to the open position.
3)
Cycle the valve to the open position by depressing the lever (7) to purge. Fluid
should begin to dispense from the tip of the valve. Continue dispensing until all
air is removed.
4)
Check fluid connection for leaks. If the valve is leaking or dripping, refer to the
Troubleshooting
section.
5)
Adjust the material pressure until the desired flow rate is achieved.
6)
Fine tune the flow rate with the stroke adjustment nut (5). First loosen the set
screw (11) with a .050” Allen key then turn the stroke adjustment clockwise to
increase flow and counter-clockwise to decrease the flow rate. If the stroke is
loosened too far out then the valve will not open.
7)
Once the stroke adjustment setting is determined, retighten the set screw (11)
using a .050” Allen key.
Note: Refer to
Troubleshooting
section for any problems.
Routine Cleaning and Disassembly
Cleaning and rebuilding the valve will be required from time to time. A spare
parts kit, part #
CAM2-SP
is available with all the normal wear parts included.
1)
If possible, flush the valve thoroughly with an appropriate solvent before
disassembly. (Refer to MSDS sheets of fluid for suggested solvent)
2)
Begin disassembly by first removing fluid pressure from the system.
3)
Remove all fluid delivery fittings, hoses, etc. from the valve.
4)
Using the tip of a 9/64” Allen key, remove the four machine screws (12) that hold
the top cap (1) to the fluid section (3).
5)
Lift off the top cap assembly and remove diaphragm (2).
6)
Using an adjustable wrench, unthread and remove the plastic luer adapter (9) from
the fluid section (3).
7)
Clean all of the wetted parts thoroughly with an appropriate solvent.
8)
Using a .050” Allen key unthread and remove the set screw (11) that threads into
the stroke adjustment nut (3).
9)
Unthread and remove the stroke adjustment nut (3) from the piston (4) which will
allow the piston and spring (8) to slide out through the bottom of the top cap (1).
10)
Using a .050” Allen key unthread and remove the two set screws (11) that thread
into the standoffs (6).
11)
Slide the dowel pin (10) out of the standoffs (6) and lever (7) to separate them
from the top cap (1).
