Maxitrol 1-1/2" Modulator Regulator Valve

Valves designed to operate on indirect fired atmospheric burner applications. Minimum input pressure is set using a minimum adjustment spring - the valves do not use a bypass. They are used in applications where the minimum input pressure to burner is between 2.0" and 4.5" w.c. Maximum obtainable outlet pressure is 7.0" w.c. above minimum input pressure. Note: This product should be installed by a licensed gas fitter.
