Electric circular high temperature air valve lined with refractory cement

Product Description:

Electric high temperature air valve lined with refractory cement can be used with manual worm gear, worm or pneumatic and electric actuator, and add radiator to protect the electric and pneumatic actuator and extend the service life of the valve. Widely used in metallurgy, heat treatment, industrial furnace, petroleum, chemical industry, cement, power waste heat boiler system, installed in high temperature flue gas pipeline, automatic control or cut off by adjusting signal. The valve has a gap between the valve plate and the valve body in the closed position to ensure the normal use of thermal expansion. Because this valve is specially used for industrial furnace system smoke exhaust, in order to achieve automatic control and adjustment of furnace pressure, so it is also called flue butterfly valve.

Body with lined disc and seat. Electric high temperature air valve lined with refractory cement has the properties of high strength, wear resistance, corrosion resistance and so on.

Fire-resistant cement electric high temperature air valve can be designed and manufactured into a square according to the needs of users. The flue baffle is equipped with manual actuator (with handwheel mechanism when diameter φ≤900mm), equipped with pointer and 0~90 indicator to indicate the opening degree of valve plate.

Electric high temperature air valve lined with refractory cement can withstand high temperature 1100℃, not stuck and not collapse.

In the process of use, the influence of thermal expansion and contraction of the valve will lead to the stem and packing locked, valve plate and seat stuck. Or the allowance leads to media leakage and leakage leakage rate is too large. Jinbin valve will choose the right material according to the temperature before processing, and calculate the expansion amount according to the material and thickness. The valve will not be stuck under the condition of low leakage rate.

In the process of use, high temperature through the stem heat conduction to the top of the stem, damage the actuator circuit or sealing ring, resulting in necrosis of the valve. Jinbin valve will lengthen the stem to increase the heat sink, reduce the damage of high temperature on the valve.
