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 low-temperature metal valve ball seat is specifically designed for low-temperature applications and performs excellently in such environments. The metal valve seat design ensures leak-proof and reliable sealing even under extreme cold conditions, while the forged steel structure provides strength. It is specifically designed to handle liquefied gases and other low-temperature materials reliably over long periods.
