Reflux 919 by Pietro Fiorentini is a control diaphragm valve especially designed for natural gas or other preliminarily filtered non-corrosive gases. It may be supplied in the direct-action (air to close), or in the reverse action type (air to open).
This device is mainly used in high-pressure transmission systems and in medium pressure gas distribution networks. Reflux 919 is Hydrogen Ready for NG-H2 blending.
Pietro Fiorentini SpA renewed its information security certification, while TIV Valves, Sartori Ambiente and Hyter received it for the first time.
Consultants from 23 countries joined Pietro Fiorentini teams to work on production and logistics improvements.
Hyter and its partners validated an AEMWE electrolyser up to 1 MW in an industrial environment, achieving hydrogen purity up to 99.999%.
