Maxitrol R500Z-3/4 Gas Pressure Regulator

Maxitrol R500Z-3/4 Gas Pressure Regulator is a versatile gas pressure regulator built for reliable fuel delivery across burners, nozzles, mixing tees, and proportional pre-mixers. With a zero governor and a nominal size of 3/4 inch, it provides precise control and stable performance. The aluminum body delivers durability in demanding environments, rated from -40 to 205°F, and the end connections are female threaded x female threaded with a compact 3-inch end-to-end distance.

UL, CSA (Canada and US), CE, and ANSI Z21.18 certifications ensure broad compatibility, while gas options include natural gas, mixed gas, LPG, and LP gas–air mixtures. A 1/8" threaded vent pipe connection and a 3.6" swing radius add installation flexibility. Inlet/outlet pressures cover typical systems: 1/2 psi (inlet), 2 psi (emergency exposure limit), and -1 to 2.5 in WC (outlet).
