QT800

QT800 is the next step up on Eltorque`s quarter-turn portfolio. The actuator is designed to operate medium sized butterfly- and ball valves with an operating torque of 250-800 Nm. The QT800 is available with Digital, Analog, MODbus and CANbus interfaces. The difference between QT250 and QT800 is that the latter is fitted with an extra gear box to produce the required torque level.

QT800 now supports dual CAN and failsafe features, which is intended to support IMO/SOLAS requirements for safe return to port (SRtP) and emergency shut down.
