Troubleshooting 

Troubleshooting Problem 

Possible Cause 

Corrective Action 

 
 
 
 
 
 
 
Valve does not cycle 

Air pressure to the air section 
is too low 

Increase the air pressure to 
60-100 psi 

 
Packing nut is too tight 

Loosen the packing nut 
until valve begins to cycle; 
retighten the packing nut 

Micrometer adjustment bolt 
has bottomed out 

Back out the micrometer 
adjustment bolt by turning 
it counterclockwise 

Material is cured in the valve 

Disassemble and clean the 
valve 

Valve was assembled without 
lubricating the O-ring seals 

Disassemble the valve, 
lubricate the seals, and  
re-assemble the valve 

 
 
 
 
Material leaks from the 
valve tip 

Packing nut is too tight 

Loosen the packing nut 

Needle and/or seal are worn 

Replace the parts as 
necessary 

Air bubble trapped in fluid 
body or in nozzle adapter 

Flip the valve upside down 
and cycle until the air 
bubbles are removed 

O-ring is worn or missing the 
nozzle extension 

Replace the O-ring 

 
Valve leaks from the  
mid-section 

Packing nut is loose 

Tighten the packing nut 
until it is snug 

Packing is worn 

Replace the packing 

 
 
 
Valve does not dispense 
anything 

Fluid pressure is too low 

Increase the fluid pressure 

Material cured in fluid section  Disassemble the valve and 

clean 

Micrometer adjustment bolt is 
set too close to zero 

Back out the micrometer 
adjustment bolt by turning 
it counterclockwise 

 
 
 
Air bubbles in fluid 

Valve is not properly purged 

Flip the valve upside down 
and cycle until the air 
bubbles are removed 

Problem with the fluid 
delivery system 

Diagnose and repair 

 
Dispense rate is too fast 

The micrometer adjustment 
bolt is set too far from the 
zero mark 

Turn the micrometer 
adjustment bolt clockwise 
toward the zero mark
