Designed specifically for deep-cold media such as LNG and liquid oxygen, this valve features an austenitic stainless steel body that undergoes special deep-cold treatment to ensure reliable sealing and operational performance under extreme conditions of -196℃. The valve stem adopts an extended neck design and is equipped with a vacuum insulation structure, effectively blocking the transmission of cold energy. The valve can be equipped with either a flat seal or a conical seal structure, allowing for selection based on different pressure ratings, and is suitable for precise flow control in liquefied natural gas storage and transportation, air separation equipment, and low-temperature chemical systems.
Forged Steel Bellows Seal Globe Valves are widely used in pipelines of industries such as power, petrochemicals, papermaking, metallurgy, aerospace, etc., as a medium for connecting or cutting off. For example, in the oil and gas industry, it can be used for cutting off or regulating pipelines; In the chemical industry, transport control systems suitable for various chemical media; In the power system, it can be applied to the cooling water system, steam system, etc. of power plants
There are two main types of forged steel check valves: forged steel swing check valves and forged steel lift check valves. The quality of forged steel parts is higher than that of cast steel parts, and they can withstand large impact forces. Their plasticity, toughness, and other
