The Eltorque Lifelong Intelligent control concept provides maintenance-free,
configurable, eco-friendly, and fully electric actuators with real-time
feedback.
•QT-series of actuators is ideal for quarter-turn valves such as butterfly
and ball-valves.
The Eltorque electric actuators can be connected in series. They offer a plug
and play solution with low installation costs and a high level of security. By
combining the Eltorque actuators with the Eltorque Hybrid Marine Cable, the
installation cost is further reduced.
The bus connected actuator eliminates the cable clutter, transportation loss
and air or oil leakage associated with conventional actuators.
The use of permanent magnet-based motor technology and efficient electric,
mechanical and firmware design, guarantees eco-friendly and cost-efficient
ownership.
Eltorque actuators have a proven track record of maintenance-free operation
with 15+ years operation.

The QT-series with self-lock is characterized by quarter-turn movement and
low energy consumption, along with their small footprint. The QT series is
suitable for butterfly, ball and other quarter-turn valves.
QT series consist of many sales articles with different functionality.

This chapter includes safety information that the user needs to know to
operate the equipment without harming personnel or the environment.
The operation of the equipment is safe provided that the recommended
operating procedures are followed. There are specific hazards however that
need to be addressed so that the user knows how to deal with them.
Electrical installations shall be designed and installed by personnel with
certifications according to applicable laws and regulations. Ensure that all
such work is done according to applicable laws and regulations.
Service must always be performed by trained personnel.
All batteries and electronic equipment may contain substances harmful to
the environment. Therefore, after removing used equipment, return them for
disposal according to local governmental guidelines.
Caution! Do not use ammonia, alkaline cleaners, lye or strong acid for cleaning as this
can damage the protective anodized layer of the product surface.
Caution! Do not use high pressure power washer directly on the actuators, as the
product is not IP69K rated.

The QT-series is the most sold product series in the Eltorque portfolio. The
QT series generation 2.5 consists of five products with maximum torque
ranging from 70 to 1000Nm. The QT series is equipped with a position
sensor that gives correct position feedback, even after a power outage. All
products can be manually operated utilizing a fixed hand wheel located
under the cover on top of the actuator, without external tools.
The QT series generation 2.5 is fragmented in to five products QT70, QT250,
QT400, QT800, and QT1000. See relevant datasheet for details.

The actuator must be integrated with the main control system in one of two
ways:
•Directly to the main control system. In this case it is important to
consider the communication protocol.
•Through a stand-alone sub-system delivered by Eltorque. This is a
standardized hardware and software platform tailored for Eltorque
actuators.
The solutions illustrated below show a bus connection with the Eltorque
Hybrid Marine Cable. This cable can be used with the CANopen and Dual
