More and more high temperature resistant hard sealed ball valves are widely used in petroleum, chemical, steel, metallurgy and hydropower fields. Compared with the soft seal (sealing material is polytetrafluoroethylene, rubber and other plastics) ball valve, the sealing material and design structure of the hard seal ball valve can be better applied to the field of high temperature resistance.

 the ball valve market is poised for growth, driven by trends that favor high-quality products and technological advancements. 

In the realm of industrial applications, the demand for high-performance ball valves has surged, particularly those designed to operate under high pressure levels and large sizes. At Yongjia Dalunwei Valve, Ltd., we specialize in the production of high-performance ball valves that meet stringent process requirements, ensuring reliability and efficiency in various operational environments.

In chemical equipment, valve as a key component to control the flow of fluid (gas, liquid or slurry), its setting and selection are directly related to the safety, efficiency, reliability and maintenance costs of the device.

The maintenance and maintenance of the valve during use is an important measure to ensure its normal operation and extend its service life. The following are the specific maintenance and maintenance methods:

 the performance test of the pneumatic hard-sealed ball valve is a comprehensive evaluation of its ability to withstand water and air pressure, maintain a secure seal, and deliver reliable performance in demanding industrial environments. The Q647Y model from Yongjia Dalunwei Valve Co., Ltd exemplifies the company's commitment to producing high-quality valves that meet the stringent requirements of modern industrial applications. With its robust design, high-pressure capacity, and versatile size options, the pneumatic hard-sealed ball valve is a reliable choice for industries seeking durable and efficient flow control solutions

A flanged ball valve is a quarter-turn valve that uses a hollow, perforated and pivoting ball to control the flow of liquid or gas.  It adopts flange connection design for easy installation and maintenance.  This valve is widely used in various industries such as oil and gas, petrochemical, water treatment, power generation, etc. due to its reliable performance and durability.

the advantages of flanged ball valves include their versatility, ease of installation and maintenance, high flow capacity, tight sealing, durability, wide range of options, and safety and reliability, making them a preferred choice for many industrial fluid and gas control applications.
