The swing-type valve disc design is combined with a low-inertia structure to ensure rapid closure and reduce water hammer effects, thereby enhancing system safety. The sealing surfaces of the valve seat and valve disc are treated with hardening or PTFE composite materials, which adapt to the ultra-low temperature contraction characteristics and maintain long-term sealing performance. The optimized flow path design reduces pressure loss, improves the efficiency of medium flow, and simultaneously reduces the risk of icing. The overall structure is compact, supporting horizontal or vertical installation, meeting the requirements of different pipeline configurations, and suitable for high-demand applications of one-way cutoff for deep-cold media.

Mainly suitable for cutting off or connecting pipeline media in various systems of thermal power plants. Applicable media: non corrosive media such as water and steam. The characteristics of forged steel valves compared to other valve products are high temperature and high pressure, unique self sealing design, and the higher the pressure, the more reliable the seal. Due to its unique performance, technical characteristics, and working conditions, the product has also developed unique features that cannot be replaced by other products.
The Insulation Jacket Ball Valve is specially designed for pipeline systems that require maintaining the temperature of the medium. It is made of high-quality stainless steel or carbon steel and combines with precise processing technology to ensure reliable sealing and smooth control under high-temperature and high-pressure conditions. The valve body adopts a jacketed insulation structure and can be filled with steam or heat transfer oil, effectively reducing heat loss. It is suitable for high-temperature fluid transportation systems in industries such as chemical, petroleum, heat supply, and pharmaceuticals. The structure is compact, the opening and closing is rapid, the sealing performance is excellent, and it is an ideal control valve for high-temperature fluid pipelines.
The structure is simple & compact with: smooth flow passages, high accuracy in flow characteris- tic curves, stable & reliable, economically practical, and easy to maintain. Based on a conventional type, it is designed and developed through modular extension which is capable of producing special structures such as: the C7 series angle type single-seat valve, bellows seal single-seat valve, and insulated jacket type single-seat valve for user selection.
