Hi, it’s still me, Yang Xiaoyang, your assistant for industrial control tasks. Lately I’ve been a bit lazy and gone straight to the useful information – that’s because it’s the end of the year! Work is too busy; I’m sure everyone has a lot to take care of at the end of the year as well, striving for our year-end bonuses. Here, the little butler wishes everyone a happy New Year in advance. May you receive generous New Year bonuses, meet kind people wherever you go, and see continuous progress in your studies! Today we are going to introduce electric butterfly valves. Many of you may already know what they are; electric butterfly valves can be used to transport slurry, and they result in the least accumulation of liquid at the pipe ends. Good sealing can also be achieved at low pressures. The streamlined design of the butterfly disc in electric butterfly valves results in low fluid resistance losses, making it an energy-saving product. The stem of the electric butterfly valve features a through-stem design; it has undergone quenching and tempering treatment, granting it excellent comprehensive mechanical properties as well as resistance to corrosion and abrasion. When an electric butterfly valve is opened or closed, the valve stem only rotates and does not move up or down; as a result, the packing on the valve stem is not easily damaged, ensuring reliable sealing. It is fixed to the butterfly plate via a taper pin, and its extended end is designed to prevent extrusion, so as to avoid the valve stem breaking free in case of an accidental breakage at the connection between the valve stem and the butterfly plate. Electric butterfly valves feature a simple structure, small size, light weight, low material consumption, compact installation dimensions, rapid operation, 90° reciprocating rotation, and low driving torque. They are used to shut off, connect, or regulate the flow of media in pipelines, offering excellent fluid control capabilities and good sealing performance when closed. The connection methods for electric butterfly valves include flange connection, clamp connection, weld connection, and lug clamp connection. The drive types include manual, worm gear drive, electric, pneumatic, hydraulic, and electro-hydraulic actuators, which enable remote control and automated operation. After reading this, I believe everyone now understands what an electric butterfly valve is. If you have any further questions or want to know more details, feel free to leave a message.
