Important Isocyanate (ISO) Information  
Important Isocyanate (ISO) Information  
Isocyanates (ISO) are catalysts used in two component materials.  
Isocyanate Conditions  
Moisture Sensitivity of  
Isocyanates  
Exposure to moisture (such as humidity) will cause ISO  
to partially cure; forming small, hard, abrasive crystals,  
which become suspended in the fluid. Eventually a film  
will form on the surface and the ISO will begin to gel,  
increasing in viscosity.  
Spraying or dispensing materials containing isocya-  
nates creates potentially harmful mists, vapors, and  
atomized particulates.  
Read material manufacturer’s warnings and material  
MSDS to know specific hazards and precautions  
related to isocyanates.  
NOTICE  
Partially cured ISO will reduce performance and the  
life of all wetted parts.  
Prevent inhalation of isocyanate mists, vapors, and  
atomized particulates by providing sufficient ventila-  
tion in the work area. If sufficient ventilation is not  
available, a supplied-air respirator is required for  
everyone in the work area.  
Always use a sealed container with a desiccant  
dryer in the vent, or a nitrogen atmosphere. Never  
store ISO in an open container.  
Keep the ISO pump wet cup or reservoir (if  
installed) filled with appropriate lubricant. The  
lubricant creates a barrier between the ISO and  
the atmosphere.  
To prevent contact with isocyanates, appropriate per-  
sonal protective equipment, including chemically  
impermeable gloves, boots, aprons, and goggles, is  
also required for everyone in the work area.  
Use only moisture-proof hoses compatible with  
ISO.  
Material Self-ignition  
Never use reclaimed solvents, which may contain  
moisture. Always keep solvent containers closed  
when not in use.  
Always lubricate threaded parts with an appropri-  
ate lubricant when reassembling.  
Some materials may become self-igniting if applied  
too thick. Read material manufacturer’s warnings and  
material MSDS.  
NOTE: The amount of film formation and rate of crystal-  
lization varies depending on the blend of ISO, the  
humidity, and the temperature.  
Keep Components A (ISO) and  
B (RES) Separate  
Foam Resins with 245 fa  
Blowing Agents  
Some foam blowing agents will froth at temperatures  
above 90°F (33°C) when not under pressure, especially  
if agitated. To reduce frothing, minimize preheating in a  
circulation system.  
Cross-contamination can result in cured material in  
fluid lines which could cause serious injury or damage  
equipment. To prevent cross-contamination:  
Never interchange component A (ISO) and com-  
ponent B (RES) wetted parts.  
Never use solvent on one side if it has been con-  
taminated from the other side.

Important Isocyanate (ISO) Information  
Changing Materials  
NOTICE  
Changing the material types used in your equipment  
requires special attention to avoid equipment damage  
and downtime.  
When changing materials, flush the equipment  
multiple times to ensure it is thoroughly clean.  
Always clean the fluid inlet strainers after flushing.  
Check with your material manufacturer for chemi-  
cal compatibility.  
When changing between epoxies and urethanes  
or polyureas, disassemble and clean all fluid com-  
ponents and change hoses. Epoxies often have  
amines on the B (hardener) side. Polyureas often  
have amines on the B (resin) side

Installation  
4. Connect the gun fluid supply hoses to the A (ISO)  
and B (RES) fluid inlets of gun.  
NOTE: Hoses are color coded: red for component A  
(ISO), blue for component B (RES). Red (ISO) usually is  
connected to the left side of the valve (as viewed from  
the back of the gun).  
1. Relieve all system pressure before installing the dis-  
pense valve.  
5. Perform Prime procedure, page 8.  
GROUNDING  
The equipment must be grounded to reduce the risk  
of static sparking. Static sparking can cause fumes  
to ignite or explode. Grounding provides an escape  
wire for the electric current.  
2. Ground the gun through connection to a properly  
grounded fluid hose and pump. See your system  
manual for further information.

Operation  
Operation  
1. Use lever (H) to close the dispense valve inlet ball  
valves (J).  
Prime  
NOTICE  
Always open and close lever (H) fully and quickly.  
Opening the valve partially or slowly will cause soft  
spots in the material and may shut down the propor-  
tioner because of a pressure imbalance.  
Perform this procedure whenever air is introduced into  
the material lines, such as after connecting the material  
supply lines to the dispense valve.  
1. Perform Pressure Relief Procedure on page 10.  
2. If a static mixer is installed, remove static mixer.  
2. Remove static mixer.  
3. With the static mixer removed, dispense into a  
waste container. Note pressure gauge readings. If  
pressures are more than 25% apart, continue to  
next step. If not, pressures are sufficiently balanced.  
3. Use lever (H) to open the dispense valve inlet ball  
valves (J).  
NOTICE  
4. If pressures are more than 25% apart, replace one  
or both plugs or restrictors with a different restrictor  
size:  
Always open and close lever (H) fully and quickly.  
Opening the valve partially or slowly will cause soft  
spots in the material and may shut down the propor-  
tioner because of a pressure imbalance.  
NOTE: An extra 0.032 in. restrictor is included with the  
gun. If necessary, use this restrictor to balance the pres-  
sures. Put the larger orifice on the side with the higher  
viscosity material.  
4. If necessary, prime the proportioner. See propor-  
tioner manual for priming instructions.  
5. Run the proportioner until clean, air-free material  
begins to exit the dispense valve.  
page 10.  
b. Select the new restrictors required to achieve  
desired back pressure and balance. See pres-  
sure drop chart in FIG. 2 on page 15.  
6. If necessary, Pressure Balance the Gun.  
NOTE: The valve should be able to achieve the desired  
flow rate at a pressure of 200-1500 psi (1.4-10 MPa,  
14-103 bar). A (ISO) and B (RES) pressures should bal-  
ance within 25% of each other.

Operation  
NOTE: Use the lowest proportioner pressure setting that  
produces the desired flow.  
Ratio Checking  
NOTE: Use ratio check nozzle 255247 with retaining nut  
512292. Purchase separately.  
NOTICE  
If the proportioner pressure setting is too high, any dif-  
ferences in viscosity will cause a pressure differential  
that will result in improper mixing.  
The output mix ratio of your proportioner can be  
checked by dispensing the two fluids separately out of  
the nosepiece into tared cups. The cups can then be  
weighed and the weights divided to get the mix ratio by  
weight.  
5. Use lever (H) to open and close dispense valve inlet  
ball valves (J) as desired to dispense materials.  
Ratio checks provide information about the ratio of an  
overall sample. Transient problems (soft spots) caused  
by starting and stopping the flow (lead-lag) may not  
show up in this kind of ratio check. Physical tests of the  
mixed fluid are the best check of correct ratio and mix  
quality.  
NOTICE  
Always open and close lever (H) fully and quickly.  
Opening the valve partially or slowly will cause soft  
spots in the material and may shut down the propor-  
tioner because of a pressure imbalance.  
Install Disposable Static Mixer  
6. If stopping dispensing for longer than the cure time  
of the materials:  
a. Use lever (H) to close dispense valve inlet ball  
valves (J) as desired to dispense materials.  
1. Perform Pressure Relief Procedure, page 10.  
b. Keep static mixer installed.  
2. Use lever (H) to close the dispense valve inlet ball  
valves (J).  
c. When ready to dispense again, Install Dispos-  
3. Coat threads of outlet manifold (F) with grease to  
prevent material curing on threads.  
7. When done using the dispense valve for the day,  
perform Daily Shutdown on page 10.  
4. Install static mixer and secure with nut (G).  
Dispense  
1. If it is possible that air may be in the fluid lines, per-  
form Prime procedure on page 8.  
2. If the gun has not yet been pressure balanced, per-  
form Pressure Balance the Gun procedure on  
page 8.  
3. If the fluid in the static mixer is cured or there is no  
static mixer installed, Install Disposable Static  
Mixer, page 9.  
4. Start proportioner and adjust to desired pressure.

Pressure Relief Procedure  
Daily Shutdown  
Follow the Pressure Relief Procedure whenever  
you see this symbol.  
NOTE: For brief shutdowns, leave the cured mixer in  
place until it is time to use a fresh mixer.  
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.  
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.  
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.  
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.  
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.  
5. Install PTFE night capt (19) and retaining nut (G).  
Flushing  
3. If the valve nozzle or fluid hose is clogged or if pres-  
sure has not been fully relieved after following the  
steps above:  
Flush the valve regularly to remove material build up.  
1. Perform Pressure Relief Procedure, page 10.  
a. Use lever (H) to close dispense valve inlet ball  
valves (J).  
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.  
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

Maintenance  
Sizing Restrictors  
Install Restrictors or Plugs  
If resin and hardener are at or near 1:1 ratio and viscos-  
ities are similar, add a few hundred psi pressure drop to  
each side to prevent check valve oscillation. Use the  
chart in FIG. 2 on page 15, or use a restrictor about  
twice the size of your spray tip, on both sides.  
Two 0.024 in. restrictors are installed with the gun. An  
extra 0.032 in. restrictor is included with the gun. If nec-  
essary, use this restrictor to balance the pressures.  
Optional restrictors in various sizes are also available.  
Restrictors create back pressure and make up for vis-  
cosity differences between A (ISO) and B (RES). See  
pressure drop chart in FIG. 2 on page 15 and see the  
Volume Balancing section. See 249765 Restrictor Kit  
on page 14.  
Maintenance  
Routine Cleaning  
Restrictor Screens  
1. Perform Pressure Relief Procedure, page 10.  
Soak the restrictor screens in solvent regularly to clean.  
If soaking is ineffective, replace restrictor screens.  
2. Remove restrictors (E).  
3. If using one or more restrictors, assemble  
o-rings (CC) and screens (BB) onto restrictors (AA).  
See FIG. 2 on page 15.  
Restrictors  
Soak the restrictors in solvent and use the included  
vise (30) and drill bit (31) to clean the orifice.  
4. If using one or more plugs (see Accessories on  
page 14), assemble o-rings (CC) onto plugs.  
Check Valves  
Soak the check valves in solvent. Use a small screw  
driver to actuate the check valve ball and spring to  
remove any restriction. Ensure fluid flows freely through  
the check valve before re-installing.  
5. Screw assembled restrictors or plugs into outlet  
manifold (F).
