1．概述Summary

“SYEVA”系列电动执行器用于控制0°～270°旋转的阀门及其他同类产品，如蝶阀、球阀、风门、挡板阀、旋塞阀、百叶阀等，可以广泛应用于石油、化工、水处理、船舶、造纸、电站、供热，轻工等各行业中。它以380V/220V/110V交流电源为驱动电源，以4-20mA电流信号或0-10V DC 电压信号为控制信号，可使阀门运动到所需位置，实现其自动化控制，最大输出扭矩达4000N·M。

"SYEVA" series electric actuator is used for controlling 0°～270° rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired position, achieving its automation, maximum output torque is up to 4000N·m..
