Overview

The D973H-16C electric butterfly valve adopts a precision J-shaped elastic sealing ring and a three eccentric multi-level metal hard sealing structure. It is widely used in industrial pipelines such as metallurgy, power, petrochemicals, water supply and drainage, and municipal construction where the medium temperature is ≤ 425 ℃, as a regulating flow and load cutoff body. The valve adopts a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life. This valve has a two-way sealing function and the product meets the national GB/T13927-92 valve pressure test standard.

1D973H-16COverview of Electric Butterfly Valve Products:

D973H-16CElectric Butterfly ValveUsing precisionJShape elastic sealing ring and three eccentric multi-level metal hard sealing structure are widely used for medium temperature≤425℃Used for regulating flow and carrying fluids in industrial pipelines such as metallurgy, electricity, petrochemicals, water supply and drainage, and municipal construction. This valve adopts a three eccentric structure, and the valve seat and disc sealing surface are made of different hardness and stainless steel, which has good corrosion resistance and long service life. This valve has a bidirectional sealing function and the product complies with national standardsGB/T13927-92Valve pressure test standard.

IID973H-16CFeatures of electric butterfly valve products:

1This valve adopts a three eccentric sealing structure, with minimal wear on the valve seat and butterfly plate.
2The sealing ring is made of stainless steel, which has the dual advantages of metal hard sealing and elastic sealing. It has excellent sealing performance and corrosion resistance in both low and high temperature conditions,Long service life and other characteristics.
3The sealing surface of the disc plate is made of cobalt based hard alloy by welding, which is wear-resistant and has a long service life
4The large-sized butterfly plate adopts a frame structure with high strength, large overcurrent area, and low flow resistance.
5、electricVType ball valveIt has bidirectional sealing function, and is not limited by the flow direction of the medium or the spatial position during installation. It can be installed in any direction.
6The driving device can have multiple workstations (rotating)90°or180°）Installation, easy for users to use.
