Features And Benefits
Cryogenic gate valve is mainly used in liquefied natural gas, liquefied petroleum gas, industrial gas separation equipment and some special low-temperature industry, our cryogenic valves to do 32” for the whole process of computerized control of the processing and cryogenic test.
Extension Pole Design
Equipped with an extension pole for easy handling and adaptable to special installation conditions, such as underground or high installation.
Low-density Packing
Low-density packing is used to reduce the risk of leakage and improve the sealing effect, which is suitable for various working conditions.
Full Carbide Seal
All sealing surfaces are made of cemented carbide, which has excellent wear and corrosion resistance and can extend service life.
Center Cavity Pressure Relief Design
It has the function of relieving pressure from the center chamber to the upstream end, which ensures pressure balance and improves operation safety.
Stem Stabilization Structure
Stem design is stable to ensure operational reliability, suitable for high-pressure environments, and improves the overall strength of the valve.
