DZ40YLow temperature gate valveProduct Overview:

Product usage and features:
Low temperature gate valves are suitable for low-temperature media such as methane, liquid natural gas, hexene, carbon dioxide, liquid ammonia, liquid oxygen, liquid nitrogen, and liquid hydrogen.
1To prevent abnormal pressure rise in the middle chamber, a pressure relief hole is installed on the inlet side of the gate
2Determine the top length of the valve cover based on the working temperature of the valve to ensure the valve?Reliable sealing of fillers
3Reasonably select materials for fillers, gaskets, and other parts according to the working temperature
4Strictly control the chemical composition and mechanical performance indicators such as low-temperature impact toughness of materials
5Adopting various piping flange standards and sealing surface types, suitable for various engineering needs
