Stainless steel internal parts and corrosion resistant coatings provide Recommended Replacement Life of 20 years. Inlet and outlet gauge taps allow easy system testing, even in underground tanks. The outlet pressure set point remains at a nominal factory setting of 10 psig / 0.69 bar.

This product is backed by a 10 year warranty.

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 1/8 inch NPT gauge taps orifice 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 casting 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
