“The Limitorque QXb electric actuator provides unmatched reliability and precision while lowering the cost of ownership in a range of demanding applications,” said Mark Stone, global product leader – electric actuation, Flowserve. “This next-generation device builds on the proven state-of-the-art Limitorque MX actuator platform to provide all the user-preferred features in a quarter-turn, smart actuator package, plus connectivity with the Flowserve Flowsync App.

“Flowserve improved the interface to streamline the user experience and accelerate commissioning by as much as 50 percent. In addition, the QXb actuator enables backward compatibility with older QX actuators, via a conversion kit, which helps reduce costs and provides future-proofing.”

The Limitorque QXb actuator is designed for versatility in demanding applications within the following industries:

• Oil and gas: upstream and midstream (choke, isolation and control valves)
• Fresh water and wastewater: isolation, air scour and control valves
• Commercial power: wind energy (cooling water for offshore high-voltage, direct current [HVDC] converter platforms)
• Chemical
• General industries

Reliable flow control automation solutions are crucial for sustainable operations. Flowserve engineered the QXb actuator to maximize dependability and efficiency while enabling the transition to a low-carbon future. Along with a streamlined user experience and advanced diagnostics, it’s designed to support customer initiatives to consume fewer resources.

A large, high-resolution liquid crystal display (LCD) with adaptive brightness control provides improved legibility as well as real-time actuator status and valve position. Its IP68-rated double-sealed enclosure and non-intrusive control knobs eliminate the risk of water or dust ingress for improved reliability; this design also removes the need for a heater. Increased precision is also achieved with 0.1 percent positioning accuracy.
