Deyue Valve focuses on the production, manufacturing, sales and service of hard sealing wear-resistant ball valves, electric high-performance ball valves and hydraulic eccentric hemisphere valves.
Using eccentric valve body, eccentric ball and valve seat, the valve rod will automatically center in the common track when rotating, and the valve rod will be tightened more and more in the closing process to achieve good sealing.The ball and valve seat of the valve are completely separated to prevent the wear of the sealing ring, which overcomes the problem of the traditional ball valve seat and the ball sealing surface being always worn. The non-metallic elastic material is embedded in the metal seat, and the metal surface of the valve seat is well protected.Pneumatic eccentric hemisphere valve is especially suitable for steel industry, aluminum industry, fiber, small solid particles, pulp, coal ash, petroleum gas and other media. The fluid resistance is small, and its resistance coefficient is equal to that of pipe sections with the same length.Simple structure, small size and light weight.Tight and reliable. At present, the sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum systems.It is easy to operate and can be opened and closed quickly. It only needs to rotate 90 ° from full opening to full closing, which is convenient for remote control.Convenient maintenance, simple structure of ball valve, generally movable sealing ring, easy removal and replacement.When the valve is fully opened or closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.It has a wide range of applications, ranging from a few millimeters to several meters in diameter, from high vacuum to high pressure.
The above is the advantage of pneumatic eccentric hemisphere valve. You can get to know it. If you are interested, you can contact Wenzhou Jiadian Machinery Manufacturing Co., Ltd.
