Company Has Taken The Lead In Developing LNG Valves Used For -196°C In China. The Design Difficulties of LNG Valves that Used for Harsh Working Conditions In LNG project, the challenge Is to design and manufacture valves with a low leakages (cluring operating at cryogenic temperatures) at medium and high pressure, either internally (seat leakage) or externally (from the stem seals). LNG valves are more and more required to be Fugitive Emission certified, according to ISO 15848 or any relevant standard. Moreover, many customers are seeking for valves of 'big' size, not only Butterfly TOV, but also Top Entry Ball Valve design. The R&D on new seals able to work at cryogenic temperature is still the top priority.
