BOTTOM VALVES/SAMPLE VALVE is mainly used for the bottom discharge, sampling and no-dead zone shut-off operation of reaction tanks, tanks and other containers. The bottom flange of the valve is welded to the bottom of the tank and other containers, so as to eliminate the residual process medium usually at the outlet of the container, the actual need of the discharge valve root, the bottom structure is designed for the flat bottom, the body is V-shaped, and provides two modes of lifting and lowering the valve disc. The inner cavity of the valve body is provided with a sealing ring that is resistant to erosion and corrosion. At the moment of opening the valve, it can protect the valve body from erosion and corrosion of the breaking medium, and carry out special treatment on the sealing ring, so that the hardness reaches HRC5-62, with high wear resistance and corrosion resistance, the valve disc seal is surfacing cemented carbide on the front surface as needed, and the sealing pair is sealed by wire to ensure the reliability of the seal and prevent scarring. At the same time, the design of short stroke valve disc is adopted.
