Ratio Governors
Description
The gas pressure governors with / without filter, and with double safety diaphragm in Pietro Fiorentini’s range are equipped with balanced plug. Governors are the ideal solution for feeding burners.
They can be used with pre-filtered non-corrosive gases and are widely used in lowpressure natural gas distribution networks to industrial, commercial and residential users.
These devices comply with standard EN 88-1.
