In a floating ball valve, the ball is not rigidly fixed to its axis of rotation and can move between the seats. Line pressure pushes the ball against the downstream seat to provide tight shut-off. The two-piece bolted body is manufactured from forgings or forged or rolled bar.
These valves are mainly used in high-pressure gas transmission systems and medium-pressure gas distribution networks with natural gas and previously filtered, non-corrosive gases.
Floating ball valves are Hydrogen Ready for NG–H₂ blending.
For the Pietro Fiorentini Group, these valves are manufactured by TIV Valves, a Group company specialising in valve production in Rescaldina, Italy.
Hyter and its partners validated an AEMWE electrolyser up to 1 MW in an industrial environment, achieving hydrogen purity up to 99.999%.
Pietro Fiorentini, Athena, 2RZ, the Department of Chemical Sciences of the University of Padua and UniSMART Foundation have joined forces in the Veneto Region-funded LEONE project — LEan Optimisation of Novel Electrolysers. Over 30 months, the partners will work to simplify electrolyser manufacturing, improve reliability and reduce dependence on critical and costly materials. The project […]
2025 was marked by evolving geopolitical dynamics and shifting international balances. In this complex scenario, the solidity of the Pietro Fiorentini Group ensured the continuity needed to face challenges and seize opportunities responsibly and with a long-term vision. Built on this resilience and the Group’s new governance structure, the 2025 Sustainability Report is titled “Many […]
