Cryogenic Extension Gate Valves

The Cryogenic Extension Gate Valves of Hanno Valve have high quality and long-life, reasonable structure, scientific design, stable work. Cryogenic Extension Gate Valves have fireproof, anti-static desig, materials suitable for ultra-low temperature environments, structure design suitable for different working conditions.

The Cryogenic Extension Gate Valves of Hanno Valve make high pressure nitrogen test at room temperature, hig pressure helium test at low temperature and perform low leakage detection for external leakage.

Application of Cryogenic Extension Gate Valves

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, liquid hydrogen, etc

Features of Cryogenic Extension Gate Valves

1. To prevent abnormal pressure rise in the middle chamber, a pressure relief hole is installed on the inlet side of the gate plate

2. Determine the top length of the valve cover based on the operating temperature of the valve to ensure reliable sealing of the valve stem packing

3. Reasonably select materials for fillers, gaskets, and other parts based on the working temperature

4. Strictly control the chemical composition and mechanical performance indicators such as low-temperature impact toughness of materials

5. Adopting multiple piping flange standards and sealing surface types, suitable for various engineering needs
