Ball Valve

ZhengFeng Valve produces trunnion ball valves and floating ball valves. The two major types of ball valves are specially designed for the corresponding operating conditions, covering almost all kinds of oil and natural gas operating conditions.Our ball valves adopt special parts different from those on the market, namely, balls with excellent materials and excellent performance, and each ball has passed the corresponding standard pressure test before assembly. Ball Valve takes ball with circular hole as opening and closing element. The ball is driven by valve stem to rotate 90° around valve stem to perform opening and closing. The valve is used to cut off or switch on the medium within pipeline, and widely used in petroleum refining, long-distance transportation pipeline, chemical, paper making, pharmaceutical, water conservancy, electric power, municipal and steel, etc. Special consideration is made to strength, safety, resistance to harsh environment during design. Its suitable for various corrosive and non-corrosive mediums. Different materials may be selected for selected for transportation of water, steam, oil, natural gas, nitric acid, acetic acid, oxidant and urea. Ball valve has compact structure and reliable sealing. Its sealing surface and spherical surface are closed normally which make it resistant to flush erosion by the medium, and easy to operate and repair. With the development of ZhengFeng for decades, the performance and pressure strength of ball valves can be compared with the top products at home and abroad.
