Use of ventilation butterfly valve

Ventilation butterfly valves are widely used in ventilation and dust removal systems for flow regulation and throttling in dust-containing gas pipelines, ventilation purification equipment, flue gas pipelines, etc. The ventilation butterfly valve is welded with excellent wear-resistant materials. It has good wear resistance, stable and reliable operation, convenient operation, flexible action, small leakage rate, long service life and convenient equipment repair. It is especially suitable for low pressure difference, large diameter and large flow situations. It is used in combination with various actuators. Combined into ventilation butterfly valves with different functions. Ventilation butterfly valves should be installed according to the manufacturer's equipment instructions. Butterfly valves with heavy weight should be installed on a solid foundation.
Ventilation butterfly valves are widely used in metallurgy, electric power, building materials, mining and other industrial pipelines to control or regulate medium gases. Made of steel plate welding, it has the characteristics of short structural size, light weight and convenient equipment. The valve has small driving torque, flexible opening and closing, and convenient operation. There is no visible gap between the oil seal retaining ring seal pairs on the valve body and the leakage rate is small. The large expansion gap between the butterfly plate and the valve body can effectively prevent jamming caused by thermal expansion and contraction. This valve can be equipped with a variety of driving equipment such as manual equipment, worm gear transmission equipment, pneumatic equipment, and electric equipment.
