Most two-stage regulator systems are made of two single stage regulators that operate in unison to reduce the pressure gradually in two stages rather than one. During the first stage, the pressure of the gas reduces to a preset level and is then passes on to the second stage. During the second stage, the regulator adjusts the pressure so the flame ignites and remains at the desired level. However, it’s no longer necessary to install two separate regulators on a unit if you use Maxitrol 2 Stage Regulators. That’s the Maxitrol SR series’ dual manifold system combines both gas pressure regulating and flame staging in a single unit. Some common applications for the Maxitrol’s 2 Stage Regulators include direct-fired heaters, hi-lo control (for outdoor heaters), LP natural gas switchover and industrial processing.
Maxitrol 2 Stage Regulators Specs
Maxitrol 2 Stage Regulators are made from solid aluminum and are available in 3/8″ thru 1″ threaded connections. All of SR series regulators are compatible with both NPT or ISO7-1 threads. The SR series is suitable for natural gas, manufactured gas, mixed gasses, liquefied petroleum gases, and LP gas-air mixtures. All models may be powered by a 24 volt AC transformer. When the unit’s coil is energized, the appliance is a lowe fire. When the coil is de-energized, it is high fire. Continous regulation is maintained to hold the electricity set outlet at constant pressure. For specific information on individual models of the SR Series Maxitrol 2 Stage Regulators model click here.
