Description

Types R122H, R222H and R622H First-Stage Regulators are Underwriters Laboratories (UL®) listed regulators designed for Two-Stage LPG systems. These First-Stage regulators reduce tank pressure to a lower pressure (usually 10 psig / 0.69 bar) for a Second-Stage regulator. Maximum allowable inlet pressure is 250 psig / 17.2 bar. Fisher™ First-Stage regulators are painted red for easy identification. Vents are screened with standard orientation over the outlet. The Types R122H, R222H and R622H regulators have a temperature rating of -20 to 160°F / -29 to 71°C, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40°F / -40°C. The design’s superior relief performance exceeds UL requirements and provides double failure overpressure protection (pressure downstream of the second regulator will be limited close to 2 psig / 0.14 bar, even if both regulators are damaged) when used with R600 Series Second-Stage regulator. Corrosion and wear resistant materials and stainless steel internal parts provide a recommended replacement life of 20 years. A large fabric reinforced diaphragm with molded lips provide precise regulation. The large precision machined orifice assists in minimizing freeze problems. 1/8 in. inlet and outlet gauge taps allow easy system testing. Large inlet and outlet wrench fetter lockup performance and durability in contaminated gas. The vent is with 3/8 in. NPT for easy installation of vent piping.
