The RM Series In-Line Manifold Regulator is a pressure compensated single
stage design (oxygen is two-stage) and is able to maintain stable delivery
pressure performance equal to a two-stage design. The unique cartridge
in this regulator permits easy, single-unit replacement of vital parts in
minutes. Seat, nozzle, filter, spring, seals and can be replaced without
special tools and without breaking the bonnet-to-body seal. The cartridge
can be re-moved and a new one installed without costly down time or
removal of the regulator from the pipeline.
