Product Description

      The commonly used telescopic butterfly valves include clamp type butterfly valves, manual flange type telescopic butterfly valves, and butt welded butterfly valves. The clamp type butterfly valve is connected between two pipeline flanges using double headed bolts; A flange butterfly valve is a valve with a flange, which is connected to the pipeline flange at both ends of the valve with bolts; The two end faces of the butt welded butterfly valve are welded to the pipeline. The streamlined design of the butterfly plate reduces fluid resistance loss, making it an energy-saving product. The valve stem is a through stem structure that has undergone quenching and tempering treatment, and has good comprehensive mechanical properties, corrosion resistance, and abrasion resistance. When the butterfly valve is opened and closed, the valve stem only rotates and does not move up or down. The packing of the valve stem is not easily damaged and the seal is reliable. Fixed with the butterfly plate cone pin, the extended end is designed to prevent the valve stem from bursting out in case of accidental breakage at the connection between the valve stem and the butterfly plate.
