FIGURE 6-1 SOLENOID VALVE

Various corrosive gases may demand more frequent replacement of VITON7

O-rings and seals inside the valve. Be sure to use an elastomer material, appro-

priate for your specific gas application. Contact your distributor or Aalborg7 for

optional sealing materials available.

Set the GFC into PURGE mode (see Figure 2-1), and attempt to flush through

with a clean, filtered, and neutral gas such as nitrogen. [Another option for fully

opening the valve is to remove the plastic cap on top of the valve, and turning the

set screw counterclockwise until it stops. See section 7.3 for valve adjustment, to

return the valve to functional use.]
