This floating ball valve adopts a high-quality cast steel or stainless steel valve body, which is manufactured through precision casting and CNC machining. It has a smooth surface without sand holes, and outstanding corrosion resistance and high-pressure resistance. The core parameters are clearly controllable: the nominal diameter ranges from DN15 to DN300, the nominal pressure can reach PN1.6-42.0MPa, and the applicable temperature range is -29℃-425℃. The sealing grade complies with ANSI Class VI. Whether it is low-temperature liquid medium or high-temperature steam, it can achieve zero-leakage sealing and ensure the safety of working conditions.

 

Its advantages go far beyond that. The unique floating ball design of the floating ball valve allows the ball to automatically fit the valve seat under the action of medium pressure. The sealing structure that becomes tighter under higher pressure greatly reduces the risk of leakage, and the sealing reliability is improved by more than 30% compared with traditional valves. The valve stem adopts a blow-out proof structure, combined with graphite + PTFE composite packing, which is not only high-temperature resistant but also effectively prevents medium leakage and extends the service life. It is also more flexible in operation - a 90-degree rotation can complete the opening and closing, with small switching torque. Daily maintenance only requires regular inspection of the packing, saving time and effort.

In terms of application scenarios, this floating ball valve can be called a "versatile player". In oil and natural gas transmission pipelines, it can withstand high pressure differences and ensure the stable transmission of media. In the feeding and discharging control of chemical reaction kettles, the corrosion-resistant material can handle strong corrosive media such as acids and alkalis. In the urban water supply and drainage system, the large-flow design meets the demand for centralized water supply, and it is not easy to be blocked even after long-term use.
