Product Overview of D673H Pneumatic Wafer Type Hard Seal Butterfly Valve :

Based on the introduction of foreign advanced technology, our company adopts precision J-shaped elastic seals and three-eccentric multi-layer metal hard seal structures. It is widely used in metallurgy, power, petrochemical, and water supply and drainage with medium temperature ≤425 ℃ And municipal construction and other industrial pipelines, used to regulate the flow and load 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 for military mail. Test Standard.

Features of D673H Pneumatic Wafer Type Hard Seal Butterfly Valve:

1. This valve adopts triple eccentric sealing structure, the valve seat and disc are almost wear-free, and it has a tighter sealing function.

2. The sealing ring is made of stainless steel, which 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 welded with 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.
