Maxitrol SR-500W-1 Gas Appliance Regulator - 2 Stage

The SR Series provides an economical means of flame staging where infinite modulation is not required. Turn down on low fire is from 25% to 75% of high fire - flow rates to 1,000 CFH.

The SR(SR500W-1) Series regulator can serve as an alternative to double manifolds on applications requiring dual stages or settings by combining gas pressure regulating and flame staging in a single unit. Examples of 2-stage heating requiring dual gas pressure include direct-fired heaters with two speed fans, hi-lo control for door heaters, LP-Nat. gas switchover and industrial processing.  Please visit www.maxitrol.com for full SR500W-1 specifications.
