The BYS series electric actuators are used to control valves and other similar products that rotate from 0 ° to 360 °, such as butterfly valves, ball valves, dampers, baffle valves, plug valves, louver valves, etc. They can be widely used in various industries such as petroleum, chemical, water treatment, ships, papermaking, power plants, heating and heating, building self-control, light industry, etc. It uses a 380V/220V/110V AC power supply as the driving power, and a 4-20mA current signal or a 0-10VDC voltage signal as the control signal. It can make the valve move to the desired position and achieve automatic control, with a maximum output torque of 800N M
