D973H-16C electric butterfly valve
D973H electric wafer type hard seal butterfly valve, adopts precision J-shaped elastic seal ring and triple eccentric multi-layer metal hard seal structure, is widely used in metallurgy, electricity, petrochemical, water supply and drainage and municipal For industrial pipelines such as construction, it is used to regulate the flow rate and load the fluid. The valve adopts a three-eccentric structure. The sealing surfaces of the valve seat and the disc are made of different hardness and stainless steel. It has good corrosion resistance and long service life. The valve has a two-way sealing function. Test Standard.
1. The valve adopts triple eccentric sealing structure, and the valve seat and butterfly plate have little wear. 2. The sealing ring is made of stainless steel. It has the dual advantages of metal hard seal and elastic seal. It has excellent sealing performance at low and high temperatures, corrosion resistance and long service life. 3. The sealing surface of the plate is made of surfacing welded cobalt-based hard alloy. The sealing surface is resistant to wear and has a long service life. 4. The large size butterfly board adopts the stern frame structure, which has high strength, large flow area and small flow resistance. 5. The valve has a two-way sealing function. It is not restricted by the flow direction of the medium and is not affected by the space position during installation. It can be installed in any direction. 6. The driving device can be installed in multiple positions (rotated 90 ° or 180 °), which is convenient for users.
