5. SET UP INSTRUCTIONS
Refer to figure 4.0
1. Install the bracket (1) to the valve if needed.
2. Connect the fluid reservoir feed tube to the valve inlet port (2).
3. Connect the one end of the valve airline to the air inlet port (3) and the other end to the valve
controller or other pneumatic device that is used to control the valve.
4. Connect appropriate dispensing tip (5) to the fluid outlet port (4) then secure it with the needle
cap (6).
5. Set the valve controller pressure at 70 psi (4.8 bars)
6. Set the fluid reservoir pressure. Do not exceed 70 psi (4.8 bars)
7. Make sure all connections are tight
8. Place container under the valve outlet and activate the valve until the fluid flows steady.
The amount of fluid that flows through the valve is determined by:
• Valve open time
• Fluid reservoir pressure
• Dispensing tip size

7. TROUBLE SHOOTING
PROBLEM POSSIBLE CAUSE CORRECTION
Fluid pressure too low Increase fluid pressure
Operating pressure too low Increase air pressure to 70 psi (4.8 bars)
Dispense tip clogged Replaced tip
Fluid cured in valve chamber Clean valve thoroughly
No Fluid Flow
The stroke adjustment is fully
closed
Open stroke adjustment
counterclockwise. One full turn max.
Fluid pressure fluctuating
Make sure fluid pressure is constant
Valve operating pressure is too
low
Increased valve pressure to 70 psi (4.8
bars)
Valve open time is not consistent
Check to make sure the valve controller
is providing a consistent output
Inconsistent
Fluid Flow
Air trapped in fluid housing Purge valve
Fluid drools after the valve
closes, eventually stopping
Air trapped in fluid housing Purge valve
Worn diaphragm Replace diaphragm
Material build up in fluid
housing
Clean fluid housing
Fluid pressure exceeds 70 psi
(4.8 bars)
Lower fluid pressure
Steady Drip
Valve re-assembled incorrectly
after cleaning
Refer to Maintenance section
Fluid leaks between
diaphragm and fluid housing
Mounting screws loose Tighten screws
Fluid leaks out of bleed hole Diaphragm ruptured Replace diaphragm
