Home My WebLink AboutRegulator SpecsBulletin LP-7: R122H 6lolcn Min Type R122H First -Stage Regulator Introduction The Type R122H is an Undeiwnters 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 internally 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 1/6 inch NPT gauge taps onficed 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. FISHER Figure 1, type R122H Fcil514ge RegWalm Superior overpressure Protection - The combination of a high capacity relief valve and large vent provide overpressure protection that exceeds t II 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 sprang and retainer and a corrosion resistant relief valve seat. Positive Draining Spring Case- When installed property 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. 4r EMERSON Process Management Bulletin LP-7: R122H Table 1.

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, allowing excess pressure to bleed out through the screened spring case vent.
