e.5.2 FSV Maintenance
The solenoid valve consists of 316 and 416 stainless steel, and FKM (or
optional BUNA, EPR or Perflouroelastomer) O-rings and seals. No regu-
lar maintenance is required except for periodic cleaning. Various corrosive
gases or liquids may demand more frequent replacement of O-rings and
seals inside the valve. Be sure to use an elastomer material, appropriate
for your specific application. Contact Omega7 for optional sealing materi-
als available.
Set the FSV for maximum flow, and attempt to flush through in both direc-
tions 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 turn the set screw counterclockwise until it stops]. If blockage
is not alleviated, return the unit to Omega7 for servicing.
