1-6940
Cryogenic Service
VeGA Cryo 1-6940 control valves are designed for very low temperatures (up to -196°C) encountered in the cryogenic industry and in natural gas liquefying plants (NGL).
Made with materials selected specifically for this type of service, Vega Cryo valves are normally tested immersed in liquid nitrogen, using helium as the test fluid in accordance with standard BS6364.
They are available with either a metal or teflon seal between the seat and the plug (seat leakage class VI under IEC 60534-4) and with low emissions (live-loading) packing certified by TA-Luft.
