Product Overview

Cryogenic ball valves are suitable for low-temperature and ultra-low temperature conditions: LNG, air separation, ethylene rapid cooling cracking gas, ethylene distillation, and low-temperature methanol washing processes. Long neck valve cover structure: ensures the sealing performance of the packing box and protects it from freezing. Automatic pressure relief valve seat: avoids abnormal pressure rise in the middle chamber- 196 ℃ liquid nitrogen cryogenic treatment: transforms residual austenite into martensite, enhancing dimensional stability.

Structural Features

Performance characteristics of cryogenic ball valve: 1. Long neck valve cover structure: Ensure the sealing performance of the packing box and protect it from freezing 2. Automatic pressure relief valve seat: to avoid abnormal pressure rise in the middle chamber.

3. Cryogenic treatment with liquid nitrogen at -196 ℃: Transforming residual austenite into martensite and enhancing dimensional stability 4. Helium leak detection: Ensure sealing performance and ensure that the valve has a wide range of applicable media.
