5.1

Victor regulator

Pressure regulator attached to the cylinder valve reduce high cylinder pressures to suitable low
working pressures for welding, cutting, and other applications.

3 Outlet connection
WARNING!
Use the regulator for the gas and pressure for which it is designed. Never alter a
regulator for use with any other gas.
Regulators purchased with open 1/8 in., 1/4 in., 3/8 in., or 1/2 in. NPT ports must be assembled to
their intended system.
1. Note the maximum inlet pressure stamped on the regulator. DO NOT attach the regulator to a
system that has a higher pressure than the maximum rated pressure stamped on the
regulator.
2. The regulator body will be stamped "IN" or "HP" at the inlet port. Attach the inlet port to the
system supply pressure connection.
3. If gauges are to be attached to the regulator and the regulator is stamped and listed by a third
party (i.e. "UL" or "ETL"). The following requirements must be met:
•
Inlet gauges over 1000 PSIG (6.87 mPa) shall conform with the requirements of UL
404, "Indicating Pressure Gauges for Compressed Gas Service."
•
Low pressure gauges must be UL recognized for the class of regulator they are being
used on according to UL252A.
WARNING!
Do not use a regulator that delivers pressure exceeding the pressure rating of the
downstream equipment unless provisions are made to prevent over-pressurization
(i.e. system relief valve). Make sure the pressure rating of the downstream
equipment is compatible with the maximum delivery pressure of the regulator.
