Home My WebLink AboutREGULATOR PAPPERWORKBulletin LP-7: R122H 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 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 118 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. FISHER' March 2010 SCANNtU BY St. Lucie Count, Figure 1. Type R122H First -Stage Regulator 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. �www.FISHERregulators.com/lpl EMERSON, Process Management Bulletin LP-7: R122H Table 1.

Type R622 Pressure Reducing Regulator Introduction Type R622 direct -operated, spring -loaded regulators provide economical pressure reducing control in a variety of residential, commercial, and industrial telief leight applications. These regulators can be used with natural, manufactured, or propane gases and have the same inlet and outlet pressure capabilities. ® www.fisherregulators.com % �0 EMERSOM Process Management Bulletin 71.1:R622 Body Size and End Connection Style(1) 112 NPT inlet and outlet Maximum Allowable Inlet Pressure(11 Operating: 125 psig (8,6 bar) Emergency: 125 psig (8,6 bar) Except 1.8 to 2.2-inches w.c.

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.
