Electric wafer hard sealing butterfly valves

Product name: electric wafer hard sealing butterfly valve Products: D973H Commercial products: Beijing sinopec valve Co., LTD Simple introduction: electric wafer hard sealing butterfly valve adopts precision of elastic sealing and three image J eccentric multi-layer metal hard seal structure, widely used in more than 400 degrees Celsius temperature of the medium of metallurgy, electricity, petroleum chemical industry, water supply and drainage and municipal construction and industrial piping, adjust flow and load flow body use. Electric wafer butterfly valve seal are introduced in detail. A,D973H, wafer hard sealing butterfly valve electric product description: We can introduce foreign advanced technology, the use of sophisticated J shape elastic sealing and triple eccentric multi-layer metal hard seal structure, widely used in more than 400 degrees Celsius temperature of the medium of metallurgy, electricity, petroleum chemical industry, water supply and drainage and municipal construction and industrial piping, adjust flow and load flow body use. This valve adopts triple eccentric structure, seat and disc sealing plate adopts different hardness and stainless steel, with good corrosion resistance and long service life, the valve is a bidirectional sealing function, the product conforms to the national GB/T13927-92 standard valve pressure test. Second, D973H electric wafer hard sealing butterfly valve features: This valve USES, triple eccentric butterfly valve seal structure, with almost no wear plate, with the view of the tight sealing function. 2, sealing ring is made of stainless steel, metal hard seal and elastic seal, whether in the dual advantages of low and high temperature, good seal performance, corrosion resistance and long service life etc. 3 and disc sealing plate by surfacing cobalt-based carbide sealing, wear resistance and long service life. 4, large size butterfly plate adopts sewing frame structure, high strength, large flow, the flow resistance. 5 and the valve with two-way seal function, installation of the flow direction of medium without limit, nor space position, can be installed in any direction. 6 and driving device can rotate multistage (90 °, 180 °) or installation for users.
