Industrial Louver Damper Valve


The Industrial Louver Damper Valve can be widely used in the dust containing cold air or hot air gas pipeline of ventilation and environmental protection engineering in metallurgy, building materials, chemical industry, power plant and other industries. As a gas medium flow regulation or cut-off device, Industrial Louver Damper Valve is especially suitable for large diameter, large flow and low pressure difference occasions.

Industrial Louver Damper Valve can be used with a variety of actuators to form different performance equipment.


Industrial Louver Damper Valveis composed of valve body, shutter plate, valve shaft, connecting rod mechanism, driving device and other main parts. The valve body is of welded structure. The disc is composed of several louver plates which move around their respective rotating shafts. The shaft end is sealed with flexible graphite woven packing. The working principle of the valve is that the output torque of the driving device is transmitted to each valve shaft through the connecting rod mechanism, and the rotation of each valve shaft drives the rotation of their respective shutters to change the cross-sectional area of the pipeline, so as to cut off the medium in a large area, reduce the medium pressure or adjust the medium flow.
