QT Modulating Quarter-turn Electric Actuator

QT series modulating type electric actuators are suitable for controlling butterfly valve, ball valve, plug valve, they can make such valves rotate at 90.The product has the following features: Small volume, light weight, high efficiency, high reliability, high protection property and low noises etc. The unit can be operated on site, and controlled in long distance. And it can be widely used in various industries, such as petroleum, chemical industry, power plant, water treatment, and paper making industry etc.

The company has developed new intelligent actuator; selection function is increased on the basis of switch type actuator, which increased more selection space for users with different demands
