It refers to the Y-type flat bottom dumping valve with its stem and passageway forming a certain angle, and its seat sealing face and inlet and outlet passageways forming a certain angle. The dumping entry has been designed as flat bottom type or pipe connecting type.

An anti-washing and anticorrosion protection plate is set in the cavity of valve body. At the moment of valve opens, the plate can protect valve from washing our or erosion, and is characterized as high abrasion-resisting and erosion-proof . 

The valves are widely used in chemical fertilizer, mining, metallurgy, aluminum oxide and other industries.
