Special Applications High Flow Oxygen Regulator - MR400 - 20 bar Outlet Pressure from G1/2 Outlet
This is typically a European style utra high flow oxygen regulator for use in heavy cutting, thermic lancing and other arduous applications being able to deliver 20 bar working pressure.
This is a large regulator constructed from brass with a "Tee" bar for pressure adjustment - the tee bar may be removed and the pressure setting locked off with the lock nut on the PA screw.
As standard the regulator is sold complete with standard bullnose connection which is rated for use with 230 bar cylinders, should you require the same regulator with the 300 bar NEVOC inlet connection then that is also possible. The regulator has a straight through inlet / outlet configuration but is supplied with a downward pointing high flow adaptor in G1/2 connections.
The pressure range is from 0 to 20 bar gauge.
The MR400 is a large single stage regulator with 2 gauges, the outlet pressure or working pressure gauge as well as the cylinder contents gauge.
When this regulator has to be used with mixed gas systems it is important the flashback arrestor is capable of working at the higher pressure this MR400 oxygen regulator can deliver plus of course the FBA needs to be of adequate size so as to be able to flow the correct volume of gas with minimal pressure drop.
To achieve high flow with longer lengths of hose, over 10m in length it would be better to operate with larger bore hoses (16 to 19mm - 5/8 to 3/4" bore) so as to increase flow and minimise the pressure drop, a short working length of 3 to 5 m may be added at the end to allow easy torch manipulation. Special fittings may be required to fit the hose while having the G1/2" connections.
For very high flow applications, generally from piped outlet points then the OLS120 regulator will be required.
