This series of butterfly valve adopts double eccentric soft sealing structure,suitable for food, medicine, chemical industry,
petroleum, electric power, textile, paper and other water supply and drainage, gas pipeline for regulating the flow and
interception of medium.
1、The structure is convenient for maintenance,without the need to disassemble the whole from the pipeline.
2、The valve disc in the open state is hidden in the valve cavity to prevent the medium from directly washing the sealing surface;
3、The valve circulates in the whole flow channel, reducing energy loss, and the head loss is almost zero.
4、The valve seat is specially treated, and the sealing surface can meet the requirements of anti-corrosion, wear resistance and
