Product features

Electric regulating butterfly valve is also called proportional electric butterfly valve, which means that the valve opening is proportional to the control fluid, or percentage. It is composed of intelligent electric actuator and butterfly valve body, and is controlled according to the input and output 4-20mA signals. It is mainly suitable for regulating the flow, pressure, temperature, etc. of various industrial automation pipelines. The connection mode of electric regulating butterfly valve mainly includes flange type and wafer type. The valve body has large flow capacity. For normal temperature and clean media, the valve plate plus soft seal (rubber ring, tetrafluoro ring) can be used to reduce leakage (up to zero leakage). Under high temperature and high pressure conditions, the three eccentric hard seal valve body can be used.
 
Features of electric regulating butterfly valve:
 
1. Novel and reasonable design, unique structure, light weight, quick opening and closing.
2. The adjustable electric butterfly valve has small operating torque, convenient operation and labor saving dexterity.
3. Different sealing seats can be used to meet the requirements of low, medium and high pressure, different medium temperature or corrosive medium.
4. The actuator is equipped with a protection device with double limit, overheat protection and overload protection.
5. For intelligent numerical control, the built-in module adopts advanced computer monolithic and intelligent control software to directly receive the standard signals output by computers or industrial instruments and other equipment, so as to realize intelligent control and accurate positioning of valve opening.
