DELO Valve Part-Turn Electric Actuator with hand wheel
QT Ex- Electric Actuator is used to control valves with 0°-270° rotation and other similar products, such as butterfly valves, ball valves ,air throttles, baffle valves, plug valves and shutter valves.
It can be widely applied in petroleu, chemical engineering, water treatment, shipbuilding, paper, power stations, heat supply, building automation, light industry and other industries.
Driven by 380V /220/ 110V AC power and controlled with 4-20mA current signals or 0-10V DC voltage signals, it can make the valve move to the required position for automatic control. The maximum output torque is up to 2,000N.M. (The product has been certified by explosion-proof certification, with guaranteed quality.)
