refractory lined damper valve

The valve body with lined plate and seat. The High temperature Refractory Lined Damper Valvehas high strength, wear resistance and corrosion resistance. The High temperature Refractory Lined Damper Valve can be designed and manufactured into a round shape according to the needs of users, so as to meet the needs of flue with different cross-section shapes. The flue baffle is equipped with manual actuator (when the diameter is not more than 900mm, it is equipped with hand wheel mechanism), pointer and 0 ~ 90 indicator board to indicate the opening degree of valve plate. The High temperature Refractory Lined Damper Valve can withstand high temperature of 1100 ℃ without jamming and collapse During use, the influence of thermal expansion and cold contraction of the valve will cause the stem and packing to lock, and the valve plate and valve seat to lock. Or too much residual leads to excessive leakage rate of medium. Before processing, Jinbin valve will select the appropriate material according to the temperature, and calculate the expansion amount according to the material and thickness. Under the condition of ensuring low leakage rate, the valve will not be stuck. In the process of use, high temperature through the stem heat conduction to the top of the stem, destroy the actuator circuit or seal ring, resulting in valve necrosis. Jinbin valve will lengthen the stem, increase heat sink, reduce the damage of high temperature to the valve
