The FE regulator by Pietro Fiorentini certified for hydrogen by Bureau Veritas

28 July 2022  -  Solutions

The range of solutions for the renewable energy sector by Pietro Fiorentini has been further extended: from the 11th of July 2022, the two-stage direct-operated gas pressure regulator Mod. FE is certified for use with mixtures containing up to 20% hydrogen.

The documentation comes from Bureau Veritas, a world leader in audit and certification services. The product conformity verification was conducted following the Type Approval for actuators and valves operating with hydrogen or hydrogen mixtures. This document describes the inspection methods and certification specifications, which can be customized according to the type of product and materials used. It also highlights the need to study the requirements according to the field of application, in compliance with existing codes and regulations.

This Type Approval follows the requirements of UNI 11655:2016 Pressure Regulating Devices (PRD) – Design, Manufacturing and Testing. Helium was used as the gas for evaluating the external and internal tightness of the regulator.


Francesco Fortuna, Europe Regional Sales Manager of Pietro Fiorentini, explained: “The two-stage regulator for medium and low pressure natural gas distribution networks is one of our historical and most popular products with our customers products. The high levels of design and quality, as well as the high safety standards, allowed us to quickly make the hydrogen ready solution ready and successfully undertake the certification process with Bureau Veritas.”


Matteo Cazzola, Hydrogen Solutions Specialist at Pietro Fiorentini, concluded ”Ensuring suitable and safe products for natural gas distribution networks with hydrogen blending, is one of the main objectives we have set ourselves. Among renewable energies, hydrogen is the element most present in nature and when produced from clean energy sources, it is a zero-impact energy vector. That’s why it that can be a very valid ally for the reduction of carbon dioxide emissions as required by the decarbonization objectives set by the European Union.”
