Maxitrol 325-7AL-210D Line Pressure Regulator

Line Pressure Regulator Maxitrol 325-7AL-210D delivers precise control for natural gas and LPG piping systems. This lever-actuated gas line regulator features a 1-1/2" nominal size and female threaded x female threaded end connections for seamless integration.

With an aluminum body rated -40 to 205°F, it functions as a reliable natural gas regulator in demanding environments while maintaining stable pressure from 1–5 PSI inlet to 7–11 in WC outlet, and an emergency exposure limit of 65 PSI. This unit is designed for 5 PSI piping systems and includes overpressure protection, ensuring safety and consistent performance across gas types: natural, mixed, LPG, and LP gas air mixtures.

Compliance and compatibility are proven by CSA (Canada and US) and ANSI Z21.18/CSA 6.3 standards. Vent pipe connections accommodate 1/2" (325-7AL) or 3/8" (OPD210D) as needed. The compact design provides a 7" swing radius and 7" height, with an end-to-end distance of 15.4" and a maximum load rating of 1,250,000 BTU/hour.
