Fl641w / F pneumatic discharge valve

Short Description:

Pneumatic discharge valve is mainly applied to the bottom of reactor, storage tank and other containers for discharge, discharge, sampling and no dead zone shut-off operation. The bottom flange of the valve is welded to the bottom of the reactor or storage tank and other vessels to eliminate the residual phenomenon of the process medium at the outlet of the vessel. According to the needs of the actual situation, the bottom structure of the valve body is designed as flat bottom type, and the valve body is V-type, and two working modes of the valve disc are provided, i.e. lifting and lowering. The inner cavity of the valve body is equipped with erosion resistant and corrosion-resistant sealing ring. At the moment of opening the valve, the valve body can be protected from erosion and corrosion by medium. The sealing ring is specially treated to make the surface hardness reach hrc56-62, which has the function of high wear resistance and corrosion resistance. When the valve disc seal is required, the cover is overlaid with cemented carbide, and the sealing pair adopts line seal to ensure the reliability of the seal and prevent scarring. At the same time, the design of short stroke disc is adopted. It is widely used in chemical, petroleum, metallurgy, dyestuff, food processing and other industries.
