1.Product Overview
D373H wafer type butterfly valve makes use of sophisticated J-shaped flexible seal ring and triple eccentric multi-level metal hard seal structure, it is widely used in industrial pipelines in which medium temperature ��?25 ��? of metallurgy, electric power, petrochemical , as well as water supply and drainage and municipal construction, to adjust flow and cut off fluid. The valve adopts triple eccentric structure, valve seat and disc sealing surface are made of stainless steel and the hardness of them is different. It has good corrosion resistance, long service life, bidirectional sealing function. It complies with national GB / T13927-92 valve pressure test standards.
2.Features
1, The valve makes use of triple eccentric structure, there is almost no wear between seat and gate, It has good sealing performance.
2, The seal ring is made of stainless steel production, with double advantage of metal seal and resilient seal. Whether at low or high temperature, It has excellent sealing performance, corrosion resistance, and long service life.
3, The disc sealing surface is made of cobalt-based hard alloy bead welding. The sealing surface is wear resistance and it has long service life.
4, The large size gate uses supporting structure. The strength is high, flow area is large, flow resistance is small..
5, The drive device can be installed in multi-position (rotated 90 ° or 180 °) ,it is easy to use.
