QT400 is suitable for a wide range of small to medium-sized butterfly and ball valves, with 50 – 380 Nm operating torque. The QT400 is available with Digital, Analog, and CAN bus interfaces.
QT400 supports dual CAN and failsafe features intended to support IMO/SOLAS requirements for safe return to port (SRtP) and emergency shut down.

In addition to the standard version, Eltorque offers specialized versions of the QT400 for use either on Open deck or in EX classified zones. These actuators are technically similar to the Standard version but are upgraded with key features to secure durability in tough conditions. An overview is listed below;
|Operating conditions||-25 to +70°C|
Designed for use on open deck and outdoor. Should not be exposed to corrosive chemicals.
-25°C to +70°C
|Certifications||IECEx – Certificate of conformity|
1. Temperature call T4-maximum surface temperature 135°C in given ambient temperature
A new coating standard makes the actuator able to handle extreme conditions, better than ever before.
For this application, we use the Norsok M-501 System 6 standard. The coating makes optimal protection of the installation with a minimum need for maintenance, the coating system is also maintenance and application friendly. This coating also ensures that health, safety, and environmental impacts are evaluated and documented.
We have added new material selection for the interface box, which increases the tensile strength. The alloy (A356) makes the interface box more resistant to corrosion. This makes it handle extreme weather and conditions better than before.
