Heating Maxitrol Pilot Loaded Regulators | 1-1/2″ Pilot Loaded Regulator (50,000,000 Btu)

The 220 Series, Utilizing A Servo-Operated Design Rather Than The More Conventional Spring-Loaded Design, Delivers Higher Outlet Pressure Than The Spring Loaded Models.

The Main Diaphragm On The Maxitrol 220 Is Loaded With Gas Pressure Rather Than With A Spring. This Gas Pressure Is Precisely Controlled By A Small Pilot Regulator In The Upper Housing. When The Regulated Outlet Pressure Of The Pilot Regulator Is Changed, By Spring Adjustment, The Outlet Pressure Of The Main Regulator Will Change Proportionately.
