Type R122H First -Stage Regulator
Introduction
The Type R12211 s ar ,:r_., ,i .-
regulator designed for T,:o-Stage _P{cos s.ster•s
The unit is designed to reduce the cork pressure to air
outlet pressure of 10 psig The compact size makes';
ideal for small domestic applications and undergrounc
tanks. The outlet pressure setting is nenadryslable
and is factory set at a nominal IC osig Screened drip.
lip vents are oriented over the outtel as standard.
Features
• 20 Year Recommended Replacement Life -The
R122H is designed using egged time proven
design concepts and constructed of corrosion
resistant materials. both internally and externally
With Proper installation and penodio inspection and
matntenance the RI22H regulator -oil meet a 20
Year Recommended Replacement Life.
• Dual Gauge Taps -Built-in 118 inch NPT gduge
laps orificed to a number 54 drill size on both
the inlet and outlet side of the regulator allow' for
easytesting
• 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 lightest Installations

• Superior Overpressure Protection - The
combination of a high capacity relief valve and large
vent provide overpressure protection that exceeds
I It Oanrlams When nard in cnryuncrinn 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 limning the problems with
conosan 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 start4o-discharge point
of the non-adjustable relief valve spring moves the
diaphragm off of the relief valve seat. allowing excess
pressure to bleed out through the screened spring
case vent.
