The Maxitrol 325-9L210E-2 is a lever-acting design line pressure regulator with overprotection device (OPD). This aluminum regulator has a 2” NPT pipe size and 1/2” vent connection. The maximum individual load capacity is up to 2,250,000 Btu/h.
The 325-L Series regulator controls the gas pressure to be within the appliance or equipment operating supply range. It is CSA certified for inlet pressure up to 5 psi and features an OPD that prevents unsafe pressure build-up within the downstream piping in time of regulator failure.
The inlet pressure varies if installed with a 12A49 Vent Limiter, for Natural gas is 5 psi (34.5 kPa) and 2 psi (13.8 kPa) for LP gas. While for outlet pressure, the spring range is from 7” to 11” w.c. (1.7 to 2.7 kPa).
Multiple gases are applicable to the 325-L Series, such as natural, liquefied petroleum gases, LP gas-air mixtures, manufactured, and mixed gases. With the low-pressure regulation of the gas regulator, it is suited for pilot flow applications.
