qt70

QT70 is suitable for a wide range of small to medium-sized butterfly and ball valves. The QT70 is available with Digital, Analog, and CAN bus interfaces.

QT70 supports dual CAN and failsafe features that support IMO/SOLAS requirements for safe return to port (SRtP) and emergency shutdown.

Enclosure protectionIP68 (10m 100hr) – Corrosion protected aluminum and steel enclosure
ColorBlack
Operating conditions-25 to +55°C
Not designed for use on open deck of ship, outdoor close to saltwater, or exposure to corrosive chemicals.
Temperature protectionMotor current is switched off in case of over-heating. Stator coils are utilized as heating elements in case of low temperatures.

In addition to the standard version, Eltorque offers a specialized version of the QT70 for use on Open deck.  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 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.
