Details

BSD373H series worm gear drive hard seal butterfly valve the introduction of Germany advanced technology, using J shaped elastic precision of the sealing ring and tHe three eccentric multi-level metal seal structure, widely used in medium temperature ≤ 425 ℃ metallurgy, electric power, petroleum chemical industry, as well as the water supply and drainage and MunIcipal construction and other industrial pipe, for regulating the flow of fluid and set off. The three eccentric valve structure, the valve seat and disc sealing surface and are made of stainless steeL with different hardness, good corrosion resistance, long service life, two-way sealing function, Products in line with national GB/T13927-92 valve pressure test standards.

Features

the three eccentric valve seal structure, seat and disc almost no wear, with more tightening of the sealing function concept. |||

The sealing ring is made of stainless steel, and has dual advantages of metal hard seal and elastic seal, both in low and high temperature conditions, both with excellent sealing performance, corrosion resistant, long service life etc.. |||
Disc sealing surface using cobalt based alloy welding, sealing surface wear resistance, long service life. |||
Large size disc using lattice structure, high strength, large flow area, flow resistance is small. |||
The valve has a two-way sealing function, installation is not affected by the flow of media restrictions, is not affected by the spatial location, can be installed in any direction. |||
The device can be driven multi station (rotated 90 ° or 180 °) installation, convenient for the user. |||
