Nominal diameter:DN15~1200mm; Nominal pressure:150Lb~300Lb, PN0.6~1.6Mpa; Body material:304; Butterfly material:304; Seat material:EPDM, Dingqing, Teflon,Ethylene-propylene,wear-resistant ethylene-propylene, fluorine rubbers, silicone rubber
Stainless steel wafer butterfly valve is a kind of simple structure, small size, light weight, small flow resistance, easy maintenance and other characteristics, the valve is composed of a disc, a stem, a valve body and a valve seat, the disc is a disc shape, the rotation of the disc around the valve axis for the open and close of the valve, it is suitable for the low pressure of the pipeline and the general closing and opening control.
