EM series multiturn actuators are used for automation of various valves including butterfly valve, ball valve, gate valve, control valves and dampers. Applications include process industries like petrochemical, chemical, water treatment, shipping, paper, power plants, steel plants, building automation and other industries. EM series actuators are available in operating voltages 3 Ph 440/415/400/380 V AC & 1 Ph 220/110 V AC. It is suitable for both ON-OFF duty and modulating duty applications with control signal options 4~20mA or 0~10V DC. EM series actuators are available in various models with torque output range from 15 Nm to 1200 Nm and speed from 40 rpm – 140 rpm. Operating range of EM series actuators can be extended when used in combination with suitable secondary gearboxes like bevel gearbox, worm gearbox and linear thrust unit. Each of these gearboxes are available in various sizes to match application requirements.
