The downward discharging valve is mainly used for the bottom discharging of the reflector, tank and other containers. It is welded to the bottom of the tank and other containers by means of the bottom flange of the valve, thus eliminating the residue of process medium at the outlet of the container. The discharging valve is designed to be flat-bottomed and V-shaped according to the actual situation. It also provides two working modes of disc, lifting and lowering. The inner cavity of the valve body is equipped with a wash-resistant and corrosion-resistant sealing ring. At the moment of opening the valve, the valve body can be protected from being washed and corroded by the medium, and the sealing ring is specially treated to make the surface hardness reach HRC56-62, which has high wear-resistant and corrosion-resistant functions. The disc seals are all overlaid with carbide when needed, and the sealing pairs are sealed by wire to ensure the reliability of the seal and prevent scarring. Meanwhile, the design of short stroke valve disc is adopted. It is widely used in chemical, petroleum, metallurgy, pharmaceutical, pesticide, dyestuff, food processing and other industries. Various operating modes, such as manual, pneumatic (spring reset, double acting, with and without handwheels), electric, hydraulic, gear, etc.


The valve is easy to operate, open freely, movement is flexible and reliable; disc assembly and maintenance is simple, sealing structure is reasonable, sealing ring replacement is convenient and practical.
