Low Temeprature LCC LCB Flange Extension Stem Gate Industrial Valve For Cryogenic Service
Cryogenic Gate Valve
Cryogenic valves are specially designed for gas treatment processes and storage and transportation of liquefied gasses such as LNG, liquid nitrogen, Oxygen,. Etc. These valves are required to be operated to give assured leakage rates. These valves which are recommended to use below -50⁰C are designed with a extended bonnet which separates the operator and stem seal from the cold temperature. 12” gas column is a standard feature for these valves. Extended bonnet as per MESC SPE 77/200 & SPE 77/209 can also be offered.
