Page 9: Booster (G-43)
Installation Manual, Maintenance and Operation MI-18 Pressure Regulating Valve – Model Horus 3.2 BOOSTER (G-43) The Booster is nothing more than a pre-regulator that automatically adjusts the process conditions as a function of the input pressure and output pressure with the purpose of reducing the pilot inlet pressure, allowing the pilot to operate in a milder condition, thus eliminating any chance of interference on the regulator piloting by the input pressure variation. -

Installation Manual, Maintenance and Operation MI-18 Pressure Regulating Valve – Model Horus 3.3 PILOTS (G-40 & G-42) The pilots series G-40 and G-42 are composed by dual diaphragm pilot that can achieve much higher accuracy than other pilots due to their constructional characteristics. -
Page 11: Filters
The HORUS pressure regulators are available with F-10 filter, mounted separate from the pilot block or compact version with the filter element already attached to the pre regulator. -
Page 12: Sense
Each throttle model HORUS SC (FF) needs three process connections: one directly to the actuator on the diaphragm, one that will be connected directly below the pilot and a third for the purpose of discharging the actuator under the diaphragm. -
