Description
Performance parameter

320D middle line double flange butterfly valve (DN50-DN3600)

Features
★ the middle line double flange butterfly valve is designed according to the requirements of large-scale pipe network, which belongs to the mesh butterfly valve.
★ high strength of valve body. The safety factor is large, which can resist large pipeline stress.
★ the valve seat adopts the structural form of overall vulcanization on the valve body, and extends to the outer edge of the valve body, eliminating the use of flange gasket. The vulcanized valve seat is solid and reliable, eliminating the leakage path and corrosion clearance.
★ the soft sealing center line double flange butterfly valve can realize 100% bidirectional switch function. It can be used in various fields of industry, especially in shipbuilding, dyke, petrochemical, heavy industry, seawater, tap water, sewage and other large-scale pipe networks.
