Governors

The governors with and without filter with double safety diaphragm in the Pietro Fiorentini range are equipped with a balanced device. They represent the ideal solution for supplying burners.

They can be used with previously filtered non-corrosive gases and are widely used in the construction of low pressure natural gas distribution networks to industrial, commercial and residential users.

These devices comply with standard EN 88-1 and are Hydrogen Ready for NG-H₂ blending.
