FISHER R622H-HGK POLX1/2 FIP 1ST STAGE PROPANE GAS REGULATOR

Fisher Regulator, 1/2 in Outlet Nominal, FPOL x FNPT Connection, 4 to 6 psi, Propane Gas Media, 1 Stages

Types R122H and R622H first-stage regulators are underwriters laboratories (UL) listed regulators designed for two-stage LP-gas regulator systems. These first-stage regulators reduce tank pressure to a lower pressure (usually 10 lbf/sq-in) 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 R622H regulators have a temperature rating of -20 to 160 deg F, but have passed Fisher internal testing for lockup, relief start-to-discharge and reseal down to -40 deg F. Time proven design constructed of corrosion resistant and wear-resistant materials, the type R622H is designed to provide a recommended replacement life of 20 years. Built-in 1/8 in FNPT gauge taps on both the inlet and outlet pressure sides allow for easy system checks. A large 3/4 in FNPT drip-lip vent reduces the chance of blockage by freezing rain or sleet when properly installed with the vent pointing down. Each type R622H is equipped for overpressure protection with a corrosion-resistant internal relief valve that provides high capacity relief and a travel stop on the closing cap. Its size and configuration make it ideal for under-the-dome installations.
