Type R122H First -Stage Regulator
Introduction
The Type R122H is an Underwriters Laboratories listed
regulator designed for Two -Stage LP -Gas systems.
The unit is designed to reduce the tank pressure to an
outlet pressure of 10 psig. The compact size makes it
ideal for small domestic applications and underground
tanks. The outlet pressure setting is nonadjustable
and is factory set at a nominal 10 psig. Screened drip -
lip vents are oriented over the outlet as standard.
Features
• 20 Year Recommended Replacement Life — The
R122H is designed using rugged time proven
design concepts and constructed of corrosion
resistant materials, both intemally and externally.
With proper installation and periodic inspection and
maintenance the R122H regulator will meet a 20
Year Recommended Replacement Life.
• Dual Gauge Taps — Built-in 1/8 inch NPT gauge
taps orificed to a number 54 drill size on both
the inlet and outlet side of the regulator allow for
easy testing.
• Durability — A fluorocarbon valve disc is utilized
to improve lockup performance in systems with
contaminated gas.
• Improved Regulation — A large fabric -reinforced
diaphragm and stabilizer clip deliver accurate and
stable regulation.
• Easy Installation — The units compact size and
easily accessible inlet and outlet wrench flats make
installation easy even in the tightest installations.

Superior Overpressure Protection — The
combination of a high capacity relief valve and large
vent provide overpressure protection that exceeds
UL standards. When used in conjunction with a
R622 or R652, the two -stage system will limit the
downstream pressure from the second -stage to 2
psig even in a double failure situation.
• Corrosion•Resistant— Added corrosion resistance
from an internal and external coating process for all
castings prior to painting, stainless steel relief valve
spring and retainer and a corrosion resistant relief
valve seat.
• Positive Draining Spring Case —When installed
properly with the spring case vent pointed down,
the design allows moisture formed in the spring
case to drain out limiting the problems with
corrosion and freezing water in the spring case.

In addition, Type R622 regulators have internal relief
across the diaphragm to help minimize overpressure.
Any outlet pressure above the start -to -discharge point
of the non-adjustable relief valve spring moves the
diaphragm off of the relief valve seat, allow ng excess
