air damper valve

The valve is welded with high-quality wear-resistant materials. It has good wear resistance, stable and reliable operation, convenient operation, sensitive action, small leakage rate, long service life, convenient installation and maintenance. It is especially suitable for low pressure difference, large diameter and large flow occasions. It is combined with various actuators to form valves with different performance

1.The ventilation butterfly valve is made of steel plate welding, which has the characteristics of short structure size, light weight and convenient installation. 2.The valve has small driving torque, flexible opening and closing, and convenient operation. 3.There is no visible gap between the sealing pairs and the leakage rate is small. 4.The expansion gap between disc and body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction. 5. The valve can be equipped with a variety of driving devices, such as manual device, worm gear device, pneumatic device, electric device.

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

1. High quality carbon steel welding, small and light, easy to decorate. Double design of anastomotic part, strengthen firmly. 2. The butterfly disc is made of double-layer high-quality heat-resistant high-temperature alloy steel, and the inner cavity is cooled by water. 3. Due to the vertical structure of the middle line, the butterfly plate has large over-current area, small current resistance, flexible switch, convenient operation, time-saving and labor-saving 4. If the temperature is too high, add heat sink to the neck to cool down and protect the driving device. 5. High temperature resistance, small volume, flexible rotation and convenient use

High Temperature Hot Air Metallurgy Damper Butterfly Valve has the characteristics of high temperature resistance, high pressure range and large nominal diameter. The valve body is made of stainless steel, and the sealing ring of valve plate adopts metal ring instead of rubber ring. Large high temperature butterfly valve is made of steel plate welding, which is mainly used for flue gas duct and gas pipeline with high temperature medium

1. Leakage less than or equal to 1% 2. The driving ways can be manual drive, worm gear drive, pneumatic drive and electric drive 3. Carbon Steel Butterfly Air Damper Valve adopts suitable materials to meet the requirements of low, medium and high medium temperature and corrosive medium
