The OG-20 oxygen concentrator uses solenoid valve to purge sieve beds and provide the PSA action required to purge nitrogen from air and capture oxygen.  

When rebuilding an OG-20 these valves can normally be cleaned and re-used.  In the event your valves are not serviceable due to age or poor condition we offer a full solenoid valve assembly to replace your valves.

Specify 120 or 220 VAC power when ordering.  Valves work on either 50 or 60 HZ.
