Q1:What is the main use of this valve?
This valve is ideal for cryogenic applications, especially for handling liquefied gases such as LNG, in low-temperature environments.
Q2:What type of seating is used?
It uses a metal seat, designed to maintain reliable sealing performance at extreme low temperatures.
Our forged steel cryogenic metal valve seats are specifically designed for low-temperature applications and perform well in such environments. The metal seat design ensures leak prevention and reliable sealing even under extreme cold conditions, while the forged steel structure provides strength. They are specifically designed for the long-term reliable handling of liquefied gases and other cryogenic materials.
