Cryogenic Globe Valves are suitable for cryogenic working conditions of -196℃. The valve stem axis of the Cryogenic Globe Valve is perpendicular to the sealing surface of the valve seat. The opening or closing stroke of the valve stem is relatively short, with a very reliable cutting action, making it suitable for cutting off, regulating and throttling media.

Structural Features

Our cryogenic globe valves adopt optimized industrial structures with multiple upgraded designs, ensuring stable, safe and durable operation under ultra-low temperature working conditions. The detailed structural advantages are as follows:

• Diversified Configuration & Expandable Functions: Globe valves have various connection and material combinations to adapt to diverse pipeline layouts and working condition demands. Valves can be equipped with additional functions, such as bellows seals for improving overall tightness requirements or built-in check functions to meet special system operation standards.

• Standard Deep Cold Treatment: All valve parts used at temperatures below -100℃ shall undergo professional deep cold treatment in strict accordance with relevant industry regulations. This process effectively prevents low-temperature brittleness of materials and volume changes caused by material phase transformation at low temperatures, avoiding structural deformation and failure in extreme cold environments.

• Optimized Long-neck Thermal Insulation Structure: A professional long-neck structure is adopted to keep the working temperature of the packing above 0℃, effectively preventing the packing from reducing sealing performance or even failing due to excessively low working temperature. At the same time, the long-neck design reserves sufficient space for wrapping thermal insulation materials around the valve to prevent cold energy loss and improve system energy efficiency. When the operating temperature is lower than -100℃, the valve stem material is treated with chrome-plated or nitriding process to improve the surface hardness of the valve stem and the matching reliability of the packing, extending the service life of sealing components.

• High-stability Sealing System: The customized sealing gaskets maintain reliable sealing performance and excellent resilience at room temperature, low temperature and during temperature alternating changes. The valve adopts double-layer valve stem packing and counter-pressure butterfly shrapnel device, realizing zero-leakage sealing effect and stable long-term operation under frequent opening and closing working cycles.
