PF FT 518 High Medium Pressure Gas Regulators

Pietro Fiorentini’s FT 518 is a lever-operated regulator controlled by a diaphragm and setting spring which controls the valve.

It is mainly used for farm tap applications, high-pressure transmission systems and for medium pressure natural gas distribution networks with previously filtered non-corrosive gases.

According to the European Standard, it is classified as Fail Open.
