D943W Electric butterfly valve
D943W Electric butterfly valves are used to control the flow, pressure and temperature of pipelines in various industrial automated production. For example: electric power, metallurgy, petrochemical, environmental protection, energy management, fire fighting system, etc
D943W Electric Butterfly Valve is a four-eccentric all-metal sealing butterfly valve with two-way tight closing function. Spatial geometry ensure that the valve plate seals only when in the closed position in contact with the seat, so that no friction or wear between the sealing, and it can produce a torque so as to have sufficient ”welding” performance, to ensure uniform consistency sealing contact and reach two-way reach zero leakage of high-end performance.
1,Triple eccentric sealing structure, the valve seat and butterfly plate are almost wear-free, and have a tighter sealing function.
2,The sealing ring is made of stainless steel, which has the dual advantages of metal hard seal and elastic seal. It has good sealing performance at high temperature and low temperature, and has long corrosion resistance and long service life.
3,The valve body is resistant to corrosion, high temperature and abrasion, and has a long service life.
4,Large sized board is adopted truss structure which is high strength,bigger flow area and low flow resistance.
5,With two-way sealing function, the valve can be installed in any direction because you do not have to consider the medium flow direction and the space.
6,Driven device can be installed in multi-position(90℃ or 180℃ rotation),convenient to use
