The electric butterfly valve belongs to one of the electric valves and electric control valves, which can be divided into two types: flange type and wafer type. In the control field of industrial automation, the electric butterfly valve has always played a very important role, earnestly performing its own work and tasks. Generally speaking, the actuator that often works together with the electric butterfly valve is a kind of electric actuator with alternating travel, but it works together after installation and commissioning. Finally, we need to know that the electric butterfly valve can be divided into two types according to its own action mode, namely, switching type and regulating type.

Moreover, the influence of the control part on the internal leakage of the valve is introduced. Because the traditional control mode of electric control valve is through valve limit switch, over torque quick closing and other control modes, such control elements will be affected by environmental temperature, pressure, humidity and other factors, which will eventually lead to misalignment of positioning, spring fatigue, uneven thermal expansion coefficient and other factors, resulting in internal leakage of the valve, Then you need to adjust the limit again.
