O Series

Oxygen Clean “O-” Series
All EV, ET, EC and EW series electronic valves with the “O-” part number option are available manufactured and assembled for use in Oxygen-enriched environments for applications
that are extremely sensitive to contamination.
• Valves are ultrasonically cleaned, assembled, inspected and tested in an enclosed controlled area with a state-of-theart positive pressure HEPA filtration system
• Both organic and inorganic contaminants such as particulate matter and Hydrocarbon oils are removed
• No organic sealants, adhesives or lubricants are used in the manufacturing process
• Component parts are lubricated with Oxygen-compatible PFPE (perfluoropoly ether) grease, only as needed for assembly
