Electric vacuum butterfly valve
詳情介紹
product description
Electric vacuum butterfly valve overview
The electric high vacuum butterfly valve is suitable for connecting or cutting off the medium flow in the vacuum system. The valve adopts the returnable electric and electronic regulating valve driving device, which can realize the control of valve opening, closing or middle position by switching the external power supply (controlled by manual switch or computer) or external input signal. The valve plate is clamped structure, clamps the sealing ring of the valve plate, can be used in the vacuum state, also can be used in the low-pressure state. And can be installed in any location. Suitable working medium is air and non-corrosive gas.
