Electric Ventilation Butterfly Valve is an intelligent flow control device integrating electric drive,precise regulation and reliable isolation,specially designed for ventilation,air conditioning(HVAC),dust removal,flue gas treatment and industrial ventilation systems.It takes an electric actuator as the core driving component,realizing automatic control of air volume,pressure and flow,and is widely used in factories,power plants,metallurgy,chemical industry,environmental protection and other fields.

Compared with manual or pneumatic ventilation butterfly valves,this electric type has obvious advantages in automatic control:it is equipped with a high-quality electric actuator(AC220V/380V,optional DC24V),which can realize stepless adjustment of the butterfly plate opening angle(0–90 degrees)and precise control of air flow.The actuator supports remote control,signal feedback(4–20mA or 0–10V),and manual emergency operation,which is convenient for centralized monitoring and management of the system,reducing manual operation intensity and improving work efficiency.

The valve body adopts a compact wafer-type or flange-type structure,which is light in weight,small in installation space and low in air flow resistance,ensuring the smooth operation of the pipeline.The valve body and butterfly plate are made of customizable materials:carbon steel for general ventilation occasions,304/316L stainless steel for humid,corrosive or food-grade occasions,and high-temperature resistant alloy plates for high-temperature flue gas(up to 450°C),which can adapt to various harsh working environments.

The sealing structure adopts soft seal(EPDM,PTFE)or metal hard seal,with excellent airtightness,effectively preventing air leakage,flue gas backflow and dust overflow.The electric actuator has the functions of overload protection,limit switch and fault alarm,which ensures the safe and stable operation of the valve.With simple structure,few wearing parts and low maintenance cost,it is an ideal intelligent control accessory for modern ventilation and environmental protection systems.
