220 Series Pilot Loaded

The 220 Series uses a servo-operated design rather than the more conventional spring-loaded design and can deliver higher outlet pressure than spring loaded models. The main diaphragm of the model 220 is loaded with gas pressure instead of spring pressure. A small pilot regulator, located in the upper housing, accurately controls the gas pressure. When the regulated outlet pressure of the servo regulator is changed by spring adjustment, the outlet pressure of the 220 main regulator will be changed proportionately. Applications include industrial furnaces and ovens.
