J0__
All models except RV131 are CSA design certified for
112 psi rated pressure underthe ANSI standard forges
Pressure regulators; and CSA listed to certify
compliance with nationally published safety,
construction, and performance standards.
They are main burner only, non -lockup type. They
should not be used as a line gas pressure regulator
ahead of low pressure controls. Use only where
downstream controls can operate at lime pressure.
Refer to other Maxitrol safes bulletins for proper types.
The RV52, RV53, & RV61 are suitable fortrtultipoise
mounting, 7heRV81, RV91, RVI 11, & RVI 31 are
recOmmended fornormal horizontal position only.
--Maxitrol"s original Straight-Thru-Flow design meets your
needs for high capacities at low inlet pressures. The
basic difference between S -T F design and other
type
regulators ties in the conical valve. The cone principal
Permits gas to flow straigh t th rough the regulator
without changing directions. Fricticnai flow resistance is
reduced, resulting in greater capacity.
The improved floWpattern provides accurate sensitive
regulation at extremely low Pressure differentials. The
ability of the regulator to handle large capacity
appliances with limited supplypressure offers a definite
advantage to designers of rommercial and industrial
gas-fired equipment.
Models up to the three inch pipe size have high
strength pressure cast aluminum housings. The RV131
four inch model is of cast iron and steel construction.

BENEFITS
Unique cortical valve design fills need of combining
good regulation with high capacity in low to
intermediate pressure range
° Allows mare pressure drop to be assigned to piping
and valves—permits reduction in manifold size
° Provides accurate, sensitive: regulation at inset
pressures as low as 3,, W.G.

Ease of installation and replacement
valves are coated with Tef[on0forlong life. Diaphragm
material is cut from the finest synthetic coated fabrics
available. All other parts are carefully specified corrosion -
resistant or plated material.
Pipe sizes of 112", 314-, 1", 1-114°, 1.1/2' 2", 2-11,2"
and 4" are available. Models through thei.-size are
threaded, the 4" RVI 31 is €fanged.
At the emergency exposure limits, there may be no
regulation, but all models will contain gas. They wil! suffer
-no interval damage and will resume regufatibh when.
normal pressure is restored.
straighi Thru-Flow appliance regulators are intended for
use with all fuel gases, and rimy also be used with air or
other noncorrosive gases within their pressure limits.
Typical applications include all types of residential,
commerclaland industrial gas-fired appliances and
equipment used on low pressure gas supply. See

SOLUTION:
I. Determine differential pressure available: Pressure Drop Chart
Inletpressure 9," W.G.
Subtract outlet pressure _ 8„ w,c. 25 10
Available dif;erentialpressure 4" w.c.
2. When determining capacity Maxitrol l
recommends that the pressure drop not exceed
112 of available differential pressure (112 of 4" j
uv.c.. = 2" w.c.).
3. Check Capacity Chart to determine which Q
regulator has a pressure drop of 2" w.c. or less at o
a flow rate of 8,000 CFH. 2
4. The RVI I I meets these standards with a p
flow rate of 12,134 GFH for the 2-11,x" pipe size at � �-5 1
2"w.c. pressure drop. The 2-112" RV91 flows m
8422 CFH at2"w.c. pressure drop. Therefore, the A l
RVI 11-2-1/2" is the correct regulator to use.
