butterfly damper

one way check butterfly damper valve is used for the ventilation duct of flue gas and other gases. Its main function is to prevent the backflow of the medium. The function of the check valve is to allow the medium to flow in only one direction and prevent the flow in the opposite direction. Usually, this valve works automatically. Under the action of fluid pressure flowing in one direction, the valve disc opens; When the fluid flows in the opposite direction, the fluid pressure and the self weight of the valve disc act on the valve seat, so as to cut off the flow.

The butterfly damper valve with chainwheel operation can be selected according to customer needs. The applicable temperature depends on the material selection of valve body. It is generally suitable for ventilation and medium flow regulation in industrial, metallurgical, environmental protection and other pipelines. The chainwheel can be used for operation at a distance from the 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

Fabricated Butterfly Dampers Valve has the advantages of compact structure, easy installation, small flow resistance, large flow capacity, avoiding the influence of high temperature expansion, and easy to operate.

The failure rate of Electric Butterfly Damper Valve is very low. It's very convenient to use. And because its sealing system is metal sealing, so the service life is longer than elastic seal, and has the characteristics of high temperature resistance. And Electric Butterfly Damper Valve can also be customized according to the needs of customers

There are no connecting rod, bolt and other components in its interior, so some component problems will not occur in the use process, so the failure rate is very low. It's very convenient to use. It is a reliable valve device. Because there is a large gap between the butterfly plate and the valve body of Stainless Steel Damper Control Butterfly Valve, there is enough expansion space, so in the process of use, it can effectively prevent the thermal expansion and cold contraction caused by the temperature change, and the butterfly plate will not be stuck. Because of the wide selection of materials, this kind of ventilation butterfly valve also has the characteristics of high temperature resistance, there will be no friction when opening and closing, and the service life is extremely long.

1. Compact and simple structure design, small volume, light weight, easy operation 2. Welding structure, good performance, low leakage rate, suitable for gas medium

Manual, electric, pneumatic series of 304SS Butterfly Damper Valve are made of steel plate welding, with the characteristics of short structure size, light weight and convenient installation. The 304SS Butterfly Damper Valve has small driving torque, flexible opening and closing, and convenient operation. There is no visible gap between the sealing pairs and the leakage rate is small. The expansion gap between butterfly plate and valve body is large, which can effectively prevent the jamming caused by heat expansion and cold contraction. The 304SS Butterfly Damper Valve can be equipped with a variety of driving devices, such as manual device, worm gear transmission device, pneumatic device, electric device. Ventilation butterfly valve is widely used in metallurgy, petrochemical, electric power, building materials, mining and other industrial pipelines, to control or regulate medium gas
