damper

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

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.

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.
