Ratio Governors
Description
Particularly suitable for any installation of burners, mixing nozzles and proportional premixers, Ratio Governors are the double safety diaphragm governors with balanced device of the Pietro Fiorentini range. They are able to maintain a constant gas/air ratio even when the air pressure varies.
Mainly used in low pressure natural gas distribution networks to industrial, commercial and residential users, they can be used with previously filtered non-corrosive gases.
These devices comply with standard EN 88-1.
