QT1000 is the next step up on Eltorque`s quarter-turn portfolio. The actuator is designed to operate butterfly or ball valves with an operating torque of 250 – 1000 Nm.

The QT1000 is available with Digital, Analog, MODbus, and CANbus interfaces. 

QT1000 now supports dual CAN and failsafe features intended to support IMO/SOLAS requirements for safe return to port (SRtP) and emergency shut down.

Temperature protectionMotor current is switched off in case of over-temperature. Stator coils are utilized as heating elements in case of low temperatures.

In addition to the standard version, Eltorque offers specialized versions of the QT1000 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;

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 a 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.
