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.

The resilient seat butterfly valve, also known as a centerline butterfly valve, is a component used for controlling flow and isolating sections in piping systems. The structural feature of the centerline butterfly valve is that the stem axis, the center of the butterfly disc, and the center of the body are all aligned in the same position. This design is simple and easy to manufacture. A common example of this type is the rubber-lined butterfly valve.
Compared with other valve products, HTHP Slab Gate Valve is characterized by high temperature and high pressure. Among them, grooved flange is designed as a unique self-tight-seal structure. The higher the pressure, the more reliable the sealing performance. Due to the characteristics of performance and technical characteristics and working conditions, the product has also formed the characteristics of other products that cannot be replaced. This type of valve should generally be installed horizontally in the pipeline. The high-temperature and high-pressure gate valve has the design characteristics of ordinary wedge-type gate valves. The valve body has a guide mechanism to prevent rotation when the gate is turned on or closed to ensure that the sealing surface of the valve seat is accurate accordingly. At the same time, the wedge valve does not rub with the valve seat before turning off, thereby reducing the wear of the cover and effectively extending the service life of the valve.
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 mechanical properties are higher than those of cast steel parts. The diameter of forged steel stop valves is generally not more than DN80, and most of them are reduced-diameter designs. Compared with cast steel stop valves of the same diameter, the flow rate is slightly lower, but the pressure and temperature range they can withstand are higher than those of cast steel valves, and their sealing performance is much better than that of cast steel stop valves, and their service life is longer. Like other stop valves, they are subject to the restrictions of the flow direction of the medium. Forged steel stop valves can be divided into straight-through stop valves (type stop valves) and direct-flow stop valves (Y-type stop valves) according to installation positions.
