The Limitorque QX Series B (QXb) actuator delivers superior reliability while lowering costs of ownership. Flowserve improved the interface to provide a streamlined user experience. As a result, commissioning is 50% faster.
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.
In addition, Flowserve designed the next-generation Limitorque QXb actuator for application versatility and to handle a broad range of demanding services, such as:
A simplified multi-language menu and an intuitive rotary navigation knob enable up to 50% faster commissioning than previous models.
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.
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.
An independent handwheel disconnects the motor and enables manual override, even during motor operation.
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.
Oil bath lubrication eliminates re-greasing while enabling mounting and storage in any orientation.
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.
Easy electronics interchangeability enables the updating of older models, reducing costs and providing future-proofing.
