[ valves ]
Today , there is still no specific standard for valves in hydrogen service . Working groups to define this standardization are being set up to accelerate the deployment of ‘ green ’ hydrogen on a commercial scale . TÜV has issued a standard , but no customer is implementing it yet .
Field experience
In the past , Velan has supplied control valves for hydrogen liquefaction plants in the USA ( Westcoast project , North Las Vegas ) and in South Korea ( SK project , Ulsan ) and is currently manufacturing valves for the Woodside project ( Ardmore , Oklahoma ).
In the field of aerospace , Velan has supplied butterfly valves for the launch pad of Ariane rockets in Kourou ( French Guiana ) and control valves for the Indian space program .
Future of LH 2
Currently , LH 2 is gaining popularity as a clean fuel and a sustainable form of energy . Although it holds much promise , the deployment of LH 2 on a large scale worldwide is still a challenge . With proven engineering expertise and hydrogen field experience , Velan is ready to be a part of the solution .

Why vacuum insulated piping ( VIP ) for LNG transfer ?
Vacuum insulated piping ( VIP ) will save money and time compared to conventional foam insulation :
1 . More effective insulation with less boil-off 2 . Shorter installation time on site 3 . Longer lifetime of pipe system 4 . Double containment 5 . Smaller pipe diameter
Our latest LNG project
