product description

Overview of the down - spread discharge valve

The lower expansion discharge valve body cavity is equipped with anti-erosion, anti-corrosion sealing ring, in the opening of the valve moment, can protect the valve body from medium erosion, corrosion, and special treatment of the sealing ring, so that the surface hardness reaches HRC56~62, with high wear resistance, corrosion resistance function. Disc seal is surfacing welded with hard alloy according to the need, the sealing pair adopts line seal to ensure the reliability of seal and prevent scarring. It is widely used in chemical industry, petroleum, metallurgy, pharmacy, pesticide, dye, food processing and other industries.
