The valve applies triple eccentric structure, the disc plate has no friction with valve seat during the whole starting and closing process, which eliminates the leakage of rotary control valves arisen from the wear of valve seat due to the starting or closing of valve seat. The valve seat applies multi-layer structure and provides the sealing face by the combination of metal and non-mental materials. It provides excellent performance under high-temperature or low-temperature work conditions. Thanking to its long service life and outstanding sealing performance, it is suitable for the control and shutoff operation of almost all gas and liquid during industrial process control.
