Zhengzhou Jinggong Valve Co., Ltd.

The bidirectional metal-sealed rotary ball valve is a high-performance butterfly valve that uses a unique rotating ball design, combining the sealing performance of a ball valve with the adjustability of a butterfly valve. The 90° rotation allows for rapid opening and closing of the fluid and precise adjustment, making it suitable for high-pressure, high-temperature and corrosive media. 1. Excellent sealing performance: It uses a metal hard seal or soft seal structure, with a leakage level of up to VI (zero leakage), and is resistant to high pressure (PN100+), ensuring reliable sealing under harsh working conditions. 2. Precise flow regulation: The unique patented design achieves linear or equal percentage flow characteristics, which is suitable for high-precision control requirements. 3. Super wear and corrosion resistance: The surface is sprayed or hardened with tungsten carbide, and the valve seat is made of special alloys, which are resistant to particle erosion and chemical corrosion, extending the service life. 4. Low-torque operation, energy-saving and high-efficiency: The bearing support structure is optimized to reduce friction resistance, and it can easily achieve automated control and reduce energy consumption when paired with pneumatic/electric actuators. 5. Compact structure and convenient maintenance: The integrated design reduces leakage points, and the modular structure facilitates quick disassembly and maintenance, reducing downtime and maintenance costs. 6. Wide applicability: It is suitable for high temperature, high pressure, high viscosity and solid particle containing media, and is widely used in petroleum, chemical, electric power, metallurgy and other industries to meet the requirements of harsh working conditions.
