Cryogenic Ball Valves

Cryogenic Ball Valves are specifically designed for Cryogenic Applications. They provide thundering performance under the most extreme cold working temperature conditions. Cryogenic ball valves are iced up under active process conditions, and are generally made of plastic or steel, the latter being the most widely used in chemical and petrochemical applications. Steel grades range from the most common type, namely carbon steel, with standard stainless steel being the second most common. Stainless steel alloys, which include nickel or copper are used in applications that require higher corrosion or heat resistance.

Beside that, cryogenic ball valve also has the typical ball valve structure, which means that it has a spherical disc to control flow. To be more specific, the sphere has a hole through the middle so that when the port is in line with both ends of the valve, flow will occur. When the valve is closed, the hole is perpendicular to the ends of the valve, so that flow is blocked.

Thus, a cryogenic ball valve has a good performance of switch on/off in the low temperature process condition.
