Manual Transmission Flange Ventilation Butterfly Valve Dust Removal Flue Gas Control Valve Flange Air Damper Regulator Valve Factory

Purpose and functions:

• The ventilation butterfly valve is made of welded steel plates and has the characteristics of short structural size, light weight and easy installation. The valve has small driving torque, flexible opening and closing, and easy operation. The expansion gap between the butterfly plate and the valve body is large. It can effectively prevent jamming caused by thermal expansion and contraction.

• It can be equipped with a variety of driving devices, such as manual, turbine transmission, pneumatic, and electric devices.

• The applicable temperature of the ventilation butterfly valve depends on the material selection of the valve body. The nominal pressure is less than or equal to 1.0mpa. It is generally suitable for ventilation in industry, metallurgy, environmental protection, chemical industry, building materials, power stations, glass and other industries, and gas pipelines containing cold air or hot air in environmental protection projects. , as a pipeline control device for regulating flow or cutting off gas media.

• Ventilation butterfly valves should generally be installed horizontally in pipelines.

Features:

• The design is novel and reasonable, the structure is unique, the weight is light, and it can open and close quickly.

• Small torque, easy operation, labor-saving and dexterous.

• Use suitable materials to meet different medium temperatures of low, medium and high, as well as corrosive media, etc.
