Wuxi Liangke Valve Q347Y High Pressure Hard Seal Ball Valve

Hard SealHigh-Pressure Ball Valve Advantages:　　1. Low fluid resistance; full-bore ball valves have virtually no flow resistance. 　　2. Simple structure, compact size, and lightweight. 　　High-pressure ball valves were introduced in the 1950s. With the rapid development of science and technology and continuous improvements in production processes and product structures, they have quickly evolved into a major type of valve within just 40 years. In industrially developed Western countries, the use of high-pressure ball valves has been steadily increasing year by year. In China, ball valves are widely used in petroleum refining, long-distance pipelines, chemical industry, papermaking, pharmaceuticals, water conservancy, power generation, municipal works, steel, and other industries, playing a pivotal role in the national economy. 　　High-pressure ball valves are primarily used to cut off or connect media in pipelines and can also be used for regulating and controlling fluid flow. Among them, the hard seal V-type ball valve features strong shear resistance between the V-type ball core and the metal seat welded with hard alloy, making it particularly suitable for media containing fibers and fine solid particles. Multi-way ball valves can not only flexibly control the confluence, diversion, and flow direction switching of media in pipelines but also close any channel to connect the other two. This type of valve should generally be installed horizontally in pipelines.

Hard Seal High-Pressure Ball Valve adopts an elastic loading structure, ensuring contact between the ball sealing surface and the valve seat under normal closing conditions. In high-temperature working conditions, it effectively compensates for thermal expansion of internal components, avoiding jamming caused by high temperatures, making it suitable for small and medium-diameter high-temperature applications.

3. In addition to the eccentric characteristics of metal hard seal eccentric ball valves, it also possesses other advantages. Furthermore, it can be used bidirectionally and is less prone to accumulating debris in the middle cavity. Depending on user working conditions, a drainage port can also be set in the middle cavity.

4. The Hard Seal High-Pressure Ball Valve features a specially hardened ball surface, and the valve seat is made entirely of special hard materials or partially welded with hard materials, ensuring an appropriate hardness difference between the sealing pairs.

5. Due to the special surface hardening treatment of the ball and the hard alloy welding on the valve seat, the valve can withstand media冲刷 well during opening and closing, making it particularly suitable for solid particles and abrasive media.

6. In addition to the special surface treatment of the ball and valve seat, other sealing materials such as flexible graphite and metal wound gaskets are used, enabling it to operate in high-temperature and high-pressure conditions with fire-resistant capabilities.
