Pilot Loaded Regulators

The 210 series is a lock-up type regulator and complies with codes using the specification. The 210 series has been designed for maximum control functions in an easy-to-use package for gas-fired boilers, steam generators, industrial furnaces, ovens and similar high demand equipment.

Balanced valve design eliminates the inlet pressure effect acting on the valve. Regulating stability is improved and hunting tendencies reduced by the use of dampening mechanisms in both the breather outlet and sensing tube. You get precise regulation over a broad range of pressures and flow rates with a Maxitrol 210, including “zero governor” application.

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.
