美国Victor维克多公司于1913创立。公司成立的缘由是创始人斯泰特纳是一个焊工，遭受焊接事故丢失眼球后着手建立：更安全的、更好的设计的焊接产品而成立的公司。他设计焊接和切割用的气体调节器很快收到市场的认可。从而维克多氧乙炔焊接设备的公司迅速成长。斯泰特纳的“安全性”的设计获得了大量的*专利：包括螺旋搅拌机，鹅颈喷嘴，安全监管。 公司名称缩短为Victor设备公司。Victor的产品线和业务量稳步增长，扩大产能是必要的。原三藩制造业务迁往新的总部在丹顿，得克萨斯州在1960年代中期。

Outlet pressure delivery ranges are not minimum or maximum outlet pressure When ordering regulators, specify part numbers. Regulators should not be used as 
limits. Regulators can be adjusted to zero psig outlet pressure and generally, a shut-off valve nor should they be used to protect downstream equipment. Unless 
to pressures in excess of those specified. The use of these regulators to control otherwise noted, high pressure gauges for all oxygen, inert gas, CO2 and N2O, and 
pressures outside of the specified ranges is not recommended. hydrogen models are graduated 200-4000 psig. High pressure gauges for fuel 

gas models are graduated 10-400 psig. Low pressure or outlet gauge ranges are 

determined by the regulator delivery range selected.

GENERAL INFORMATION 

How to read the Flow Data Charts: 

The regulator flow data is provided to assist in determining the proper regulator for the required application. The data is given for reference purposes 
only. If additional information is necessary contact your local distributor or the Customer Service Department at 1-800-426-1888 

The regulator flow data was established by connecting a valve to the regulator outlet. The valve was opened and the flow rates measured. The amount 
of pressure drop is shown on the curves as the flow increases. 

REGULATORS 
Example 
An SR 450D with an inlet of 2000 psig and an internal pressure setting 
of 125 psig (no flow) will flow 1000 SCFH, but the delivery pressure will 
drop to 115 lb As the flow increased to 2000 SCFH, the pressure will 
drop to 108 psig. 
With an inlet pressure of 200 psig and an initial setting of 125 psig, the 
regulator will flow 1000 SCFH with a pressure drop to 98 psig. At 2000 
SCFH flow, the pressure will drop to 78 psig. If a delivery pressure other 
than the ones shown on the flow charts is required, use an average curve 
rate between the upper and lower pressures shown. 
FLOW (SCFH) 
Delivery Pressure Rise 

Single stage regulators have an increase in delivery pressure as the 
cylinder pressure decreases. Listed below is the amount of pressure 
increase per 100 psig decrease in cylinder (inlet) pressure. 

ESS7-125 .95 psig 
ESS7-200 1.54 psig 
ESS4-125-540 .59 psig 
ESS3-125-540 .53 psig 


SR 4 Series J & K Range 4.8 psig 

SR 5 Series 1.0 psig 
SR 250 Series 0.5 psig 
SR 350 Series 0.8 psig 
SR 450 Series 0.6 psig 
SR 600 Series 0.58 psig 
SR 700 Series 1.2 psig 


The change in delivery pressure of a Two Stage regulator from 
full to empty Cylinder (inlet pressure) is negligible. 

For Conversion to Other Gases 

All flow capacity information is given in SCFH of free air (1.00). For 
conversion to other gases multiply the air flow by the correction factor 
listed below.

*Indicates pressure drop of less than 2.0 per sq. in. 
**Indicates pressure drop of less than 0.2 per sq. in. 
To obtain the recommended inlet pressure at the equipment, add the pressure drop figure (shown above) to the delivery pressure at the regulator. Do not exceed 15 psig for acetylene.

Innovative EDGE. Series Regulators Offer 
Safety and Advanced Design 
Single Stage Regulators 
Recommended for applications where slight delivery pressure 
increases (due to decreasing cylinder pressures) would not affect the 
performance characteristics of the work or test results. 
Victor. has been the leader in gas equipment for one hundred years, 
and its tradition of unparalleled safety remains a cornerstone of the 
brand today. With the Victor Professional EDGE Series Regulators, 
Victor continues to offer the safest, most reliable and highest quality gas 
control technology, giving you more value for your purchase. In addition, 
standardized designs and components throughout the EDGE family 
greatly simplify regulator service and repair. 

Gauges are recessed into the body for the highest level of safety and protection 
possible

More efficient internal flow paths translate to improved flow consistency from full to

Same sintered inlet filter used in all Victor industrial regulators 

4 
Innovative design elements enable the regulator to meet or exceed oxygen-related 
safety standards CGA E-4, UL 252, and the stringent ASTM G-175 Promoted Ignition 
Test 
5 
Housing cap is made from high strength zinc-aluminum alloy that has nearly twice the 
yield strength of forged brass 

6 Time-tested fabric reinforced neoprene diaphgram provides superior sensitivity and 
control 
7 
Seat assembly and friction damper are the same tried and true components used for 
decades in SR 350 and SR 450 

8 Internals remain protected from weather elements through an internal vent system 
protected under the knob, which is channeled to promote water run-off 
9 
SLAM. Knob designed with multi-stage crumple zones which absorb impact energy 
in the event the cylinder falls over. Helps protect pressure integrity of both regulator 
and cylinder valve.

Two Stage Regulators 

Recommended for applications that require a constant delivery 
pressure over a range of decreasing inlet pressures. This precise 
two stage regulator provides superior operating characteristics for 
applications where change in delivery pressure would affect 
performance characteristics of work or test results.

Flow Products 

What Does Victor Have to Offer? 

Victor. has a full line of flow products for virtually any application. 
Whether it is welding, industrial or laboratory use, Victor has a flow 
meter, flow gauge or surge limiting regulator for your needs. 

Victor offers a range of products for the delivery of shielding gas in 
the arc welding process or any application where gas flow rates, versus 
delivery pressure, are the primary consideration. These products are 
available for pure or mixed gases and for working with either high 
pressure cylinders or low pressure “piped shop” environments. 

OFFERING INCLUDES: 

....Regulators with flow meter 
....Flow Meters 
....Flow Gauge Regulators 
....Single or Two Stage designs

A regulator equipped with a flow gauge is not accurate when a back 
pressure in excess of 2 psig exists at the outlet. Back pressure is caused 
by a restriction in the equipment downstream of the flow gauge. Metering 
valves, kinked hoses or even very long hoses are restrictions that can 
cause back pressure. In applications where back pressure in excess of 
2 psig can be expected, a regulator equipped with a flow meter should 
be used.

WARNING: High gas withdrawal rates may cause regulator freeze up 
and will require cylinder manifolding. Consult your gas supplier. See

What Does Back Pressure Compensation Mean? 
When a flow meter is back pressure compensated, it is not affected by any downstream restrictions that result in a pressure buildup. In a device 
that is not compensated, the back pressure will result in inaccurate readings on the flow tube or gauge. 
All Victor FM Series flow meters are back pressure compensated to ensure accurate reading at all times, even if line restrictions are present. 
Control Valve 
is before the 
flowtube and 
varies the size 
of incoming 
pressure flow 
passage to 
control flow 
NON-COMPENSATED 
For Back Pressure 
....Varying inlet pressures tolerable 
....Requires flowing to atmosphere 
(no restrictions) to be accurate 
....Flow gauge regulators operate in this 
manner

are calibrated to operate at 25 psig inlet pressure to minimize surge, 
except the FM 200 which is calibrated to operate at 80 psig.
