Theory of Operation 
 

The FC100 is a high pressure, front closing stainless steel dispensing valve  that 

can be used in a wide variety of applications. Applications include general dispensing of 
dots, potting, bead placement, and gaskets.    

The FC100 has a divorced design comprising of two major sections.  These include: 

1)  Air section (red anodized portion) 

2)  Fluid section (stainless steel portion) 

The air section is an aluminum body with a simple piston/cylinder combination 

used to open and close the valve. A stroke adjustment bolt in the upper air body controls 
how far the piston and needle assembly can retract thus regulating the rate of fluid flow.  

The fluid section is a stainless steel body,  which includes a needle and seat 

combination to control fluid flow.  Fluid dispenses as the needle retracts out of the seat, 
then stops as the needle moves back into the seat. The stroke adjustment bolt regulates the 
distance that the needle can retract out of the seat thus controlling the orifice size and rate 
of fluid flow. Fluids can include but are not limited to solvents, epoxies, UV adhesives, 
silicones, RTV, grease, etc.   

Wetted parts on the FC100 include: 

- 303, 304 stainless steel 

- Teflon 

- Kalrez
