Also known as a priority valve, the model 211 is a fully
balanced, economical regulator. It serves a wide variety of
uses, however its main use is on small compressors. The
regulator will improve moisture separator efficiency and
filter life as much as 450%. This is done by maintaining
pressure in the separator and filter at 1800 PSI or more
when tank pressure is lower. It has two outlet ports
permitting attachment of a filling yoke and gauge directly
to the regulator. This eliminates costly fittings.
