FT 518 Direct Operated High - Medium Pressure Gas Regulators

Brand: Pietro Fiorentini S.p.A.
When requesting information, please download the Fillable PDF to provide details about your regulator use case. Instructions for completing the form are found in the footer of the document. Once completed, please upload the document with the Request for Information.
FT 518 is a lever-operated device for high and medium pressure with multiple replaceable orifices.

FT 518 is an unbalanced pressure regulator.

This regulator is suitable for use with previously filtered, non-corrosive gases. It is a truly top entry design which allows an easy maintenance of parts directly in the field without removing the body from the pipework.

When the built-in token relief valve is active, it prevents undesirable slam shut trip due to minor internal leakages or ambient temperature variation.

The modular design of FT 518 pressure regulators allows to retrofit either slam shut valve or integral full monitor.
Features
  • Compact and Simple Design
  • Operates with High Differential Pressure
  • Built-In Filter
  • Token IRV
  • Top Entry
  • Built-in Accessories
  • Easy Maintenance
  • Biomethane Compatible and Available with Specific Versions for Full Hydrogen or Blending
