Cryogenic butterfly valve is one of the important flow control equipment in cryogenic pipeline systems, especially suitable for services requiring valves featuring high sealing performance, swift on-off and low flow-resistance. EDVC most advanced design principle and most stringent manufacturing standard to design and manufacture cryogenic butterfly valve which helps EDVC cryogenic butterfly valve build up a reputation for reliable sealing performance, low operation torque, high stability in cryogenic service and long lifespan. Presently, EDVC cryogenic butterfly valves have been installed in several LNG liquefaction plants and terminals.
