HEQ Series quarter-turn electric actuators deliver output torque ranging from 50 Nm to 10000 Nm. Adopting a modular design, the product boasts abundant expandable functions. It is compatible with quarter-turn valves including butterfly valves, ball valves and air dampers. Widely applied in petroleum, chemical, power, metallurgy, pharmaceutical, papermaking, energy, water treatment, marine, textile, food processing, building automation and other industries.

◎ Multi-language operation menu with real-time display of valve position, alarm messages, operation status and control mode, featuring intuitive interface that is easy to learn and operate.;

◎ Equipped with an absolute encoder instead of conventional potentiometer as position sensor, it supports arbitrary angle positioning with zero dead zone, delivering higher control accuracy and longer service life.;

◎ Functions and parameter settings of the electric actuator can be configured via remote controller or local knob without opening the cover for commissioning, realizing a true non-intrusive design.;

◎ The control system of the electric actuator integrates automatic phase sequence identification, phase loss, overheating and overload protection, as well as ESD emergency operation function.;

◎ Supports multiple control modes with free switching between on-off and modulating control. Multiple wiring schemes for remote digital signals are available, including passive contact control, two-wire control and external voltage input control.;

◎ Local buttons and knobs adopt non-penetrating design to improve the overall sealing performance of the unit.;

◎ Equipped with programmable monostable relays to freely configure feedback signals, facilitating DCS system monitoring of the electric actuator.;

◎ A monitoring relay is configured for the electric actuator to transmit integrated fault signals to the DCS system.;

◎ All input and output signal channels are optically isolated and can withstand 2000V surge voltage.。
