A new quarter-turn, smart electric actuator
The new Limitorque QX Series B (QXb) electric actuator provides unmatched reliability and precision, while lowering the cost of ownership in a range of demanding applications, according to this company. The QXb actuator enables backward compatibility with older QX actuators, via a conversion kit, which helps reduce costs and provides future-proofing. The QXb actuator (photo) is engineered to maximize dependability and efficiency while while supporting decarbonization initiatives. 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% positioning accuracy. — Flowserve Corp., Dallas, Tex.
