Low-load ventilation butterfly valve

Our low-load ventilation butterfly valve has a midline structure for the valve body. It is made by bending steel plates and welding them to the flange plates. It adopts an external bearing structure to reduce the resistance during valve opening and closing. The valve plate has no friction when closed, and the torque is small. It is suitable for switching and flow regulation in ventilation systems, air conditioning systems, and high-temperature smoke gases. Low-load butterfly valves are generally used in pipelines for ventilation and to regulate the flow of media in industries such as metallurgy, environmental protection, petrochemicals, power, building materials, and mining.
