Electric actuator QXb

rotaryDCIP68

The Limitorque QX Series B (QXb) non-intrusive, quarter-turn electric actuator from Flowserve provides unmatched reliability and precision while lowering the cost of ownership in a range of demanding applications. This next-generation device builds on the proven, state-of-the-art Limitorque QX and MX actuator platforms to provide all the user-preferred features in a quarter-turn, smart actuator package. Faster commissioning A simplified multi-language menu and an intuitive rotary navigation knob enable up to 50% faster commissioning than previous models. Improved reliability A double-sealed IP68 enclosure with a separate terminal compartment and non-intrusive control knobs prevent dust and water ingress, eliminating the need for a heater. More accurate positioning Advanced brushless DC motors provide more accurate positioning and improve safety while permitting a global range of voltages (single-phase and three-phase ACV and DCV) to be connected without modification. Enhanced safety An independent handwheel disconnects the motor and enables manual override, even during motor operation. Improved visibility A large, high-resolution LCD screen with adaptive brightness control is easy to read from up to 9 m (30 ft). It can be rotated 180 degrees for viewing in any orientation. Reduced maintenance costs Oil bath lubrication eliminates re-greasing while enabling mounting and storage in any orientation. Expanded real-time status display The advanced display provides real-time torque graphs, alarm and event logs, and other data in high resolution. There’s also a real-time clock that time-stamps data logs for asset management functions and lifecycle analysis.
