    Electric Ventilation Butterfly Valve
    Electric Ventilation Butterfly Valve

    采用与阀体相同材料加工成密封圈,其适用温度和耐腐蚀性岁阀体选材而定,公称压力<0.6Mpa,其泄漏量控制在最大流通量的2%以内,应用于工业、冶金、环保等管道作通风调节介质流量之用。 The electric ventilation butterfly valve is made of the same material as the valve body into a sealing ring. Its applicable temperature and corrosion resistance depend on the material selection of the valve body. The nominal pressure is less than 0.6Mpa. Its leakage is controlled within 2% of the maximum circulation. , Metallurgy, environmental protection and other pipes for ventilation to regulate the flow of media. It has the characteristics of simple structure, light weight, small operating torque, rapid opening and closing, flexible action, large circulation capacity, high adjustment accuracy and so on. It is suitable for the regulation and control of flue gas, dust, air or fluids containing suspended particles and dense, slurry-like fluids.


    工作原理: Working principle of electric ventilation butterfly valve :

    由角型程电子式电动执行器和通风蝶阀机构组成。 The electric ventilation butterfly valve is composed of an angle-type electronic electric actuator and a ventilation butterfly valve mechanism. Mechatronics structural design, with internal servo operation and position signal position feedback, position indication, manual operation and other functions, strong function, reliable performance, accurate control, AC220V or AC380V power supply voltage as power, accept control system input (4-20mA or 1-5VDC) current signal or voltage signal, can control the operation, realize the proportional adjustment control or switch control of the process fluid medium.


    产品特点: Product Features of Electric Ventilation Butterfly Valve :

    ★ The valve has small driving torque, flexible opening and closing, and easy operation.
    ☆ It can effectively prevent the stuck phenomenon caused by thermal expansion and contraction.
    ◆ It has the characteristics of short structure size, light weight and convenient installation.
    ◇ Welded by steel plate, with short structure size, light weight and easy installation.
    ■ Oil seal retaining ring is set on the valve body, there is no visible gap between the sealing pairs, and the leakage rate is small.
