Type R122 First-Stage Regulators are Underwriters Laboratories (UL®) listed regulators designed for Two-Stage LPGas Regulator systems. These First-Stage regulators reduce tank pressure to a lower pressure (usually 10 psig) for a Second-Stage regulator. Fisher® brand First-Stage regulators are painted red for easy identification. Vents are screened with standard orientation over the outlet. The Type R122 regulators have a temperature rating of -20 to 160ºF, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40ºF.
Type R122H - Designed for use as the first stage portion of a two-stage regulation system on domestic applications, the R122H’s size makes it perfect for tight installations. Stainless steel internal parts and corrosion resistant coatings provide a Recommended Replacement Life of 20 years. Inlet and outlet gauge taps allow easy system testing. Outlet pressure remains at the factory setting of 10 psig. Each unit contains a relief valve and a large vent. Fisher’s exclusive fabric-reinforced diaphragm and cast orifice provide accurate regulation.
