1. The unique jacket structure design enables the introduction of steam, heat transfer oil or other insulation media, effectively maintaining the fluid temperature inside the pipeline and preventing the medium from solidifying or losing heat.
2. It adopts PTFE (polytetrafluoroethylene) or metal hard sealing valve seats, which are resistant to high temperatures and corrosion, ensuring no leakage during long-term use and meeting the requirements of harsh working conditions.
3. The valve body is forged from high-quality stainless steel or carbon steel and undergoes special heat treatment processes, with a high-temperature resistance of over 300℃, strong pressure-bearing capacity, and suitability for high-pressure pipeline systems.
4. The full-diameter structure design ensures that the fluid passage is consistent with the inner diameter of the pipeline, reducing pressure loss and ensuring smooth fluid flow, suitable for high-viscosity or easily crystallizing fluids.
5. It provides various driving methods such as handles, worm gears, pneumatic or electric, with flexible opening and closing and rapid switching. The modular design is convenient for disassembly and maintenance, reducing usage costs.
6. The surface of the ball is hardened, wear-resistant and corrosion-resistant, and the valve stem has a blowout prevention design, ensuring long-term stable operation, reducing failure rates and replacement frequencies.
7. It is suitable for steam, heat transfer oil, chemical fluids, petroleum, food and other industries, meeting the needs of different media and temperature environments.

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.
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.
