EDVC Cryogenic ball 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 ball valve which helps EDVC cryogenic ball valve build up a reputation for reliable sealing performance, low operation torque, high stability in cryogenic service and long lifespan. Presently, EDVC cryogenic ball valves have been installed in several LNG liquefaction plants and terminals.

Description

LOW TEMPERATURE CRYOGENIC BALL VALVE

Fully designed to cover BS6364 requirements for full tightness in medium and severe cryogenic service.

This execution has been fully tested at -196°. Extended stem length is adapted to the valve size according to BS6364 – thermal fins isolate the stem tightness from the cold temperature.
