HEQ Series S type intelligent linear valve electric actuators with digital integrated chip, absolute encoder, English operation menu and display, simple adjustment, easy operation, high enclosure protection, high reliability, stable performance and other advantages, this series of valve actuators are the new generation of our company and can be used for driving and controlling the butterfly valves, ball valves and plug valves.(part-turn valves with 90° movement), with the functions of local control and remote control both, they are widely used in the firlds such as oil, chemistry, power generation, water treatment, paper making,etc

S type intelligent valve electric actuators with non-intrusive design, all electrical components are sealed inside of the aluminum body, operating by remote control or selector switches with magnetism to make the device control more accurate, move reliable.

IP67 enclosure protection.

English display operation menu, display valve position value, alarm information,operation status and mode, intuitive, easy to learn, easy to understand, easy to operate;

The absolute encoder replaces the traditional potentiometer as the position sensor to achieve arbitrary Angle positioning,no dead zone,higher control accuracy and longer life;

Function and parameter setting of electric device,through remote control or on-site twisting operation,no need to open the lid debugging,truly realize non-invasive design;

The control system of the electric device has automatic identification of phase sequence,phase break,overheating. overload protection,ESD emergency operation function;

A variety methods of control,on/off,modulating switch remote switch a variety of wiring methods,can use dry control,two-line control,external voltage input control;

On-site keys and knobs adopt non-penetrating design to improve the sealing characteristics of the whole machine;

Provide programmable monostable relay,can be any configuration feedback signal,convenient DCS system to monitor DENso;

Set up electric device monitoring relay to provide comprehensive fault signal for DCS system; The input/output signal channels are photoelectric isolated and can withstand 2000V surge voltage.
