HTHP Wear-Resistant Ball Valves are special valves designed for high temperature and high pressure environments, which can effectively control the on/off of high temperature and high pressure fluids. Capable of stable operation under harsh working conditions, meeting the precise control requirements in industrial production processes. Widely used in industries such as petroleum, chemical, natural gas, and electricity.
It is mainly used for storage and transportation of oil and gas in the chemical industry, metallurgy, paper making, food processing, shipbuilding and other industries, used to open or close, and with pneumatic and electrical devices can also achieve the long-distance operation, to ensure personal safety.
Designed specifically for deep cold medium working conditions such as LNG, liquid nitrogen, and liquid oxygen, it adopts special stainless steel or low-temperature alloy valve bodies. Through deep cold treatment, it ensures reliable sealing even in an extreme environment of -196℃. The innovative lateral maintenance port structure allows for quick replacement of the sealing components without disassembling the valve, significantly improving maintenance efficiency. The optimized double eccentric butterfly plate, combined with multi-level metal hard seals, achieves zero leakage and long service life under ultra-low temperature conditions. At the same time, it is equipped with a longened valve stem heat insulation structure, effectively blocking the conduction of cold energy.
