Limitorque QX Electronic Valve Actuator

The Flowserve Limitorque QX quarter-turn smart electronic valve actuator continues the legacy of the industry’s state-of-the-art, non-intrusive, multi-turn MX actuator by including an absolute encoder for tracking position without the use of troublesome batteries.

The QX design provides enhanced safety and reduced downtime through improved diagnostics, built-in self-test (BIST) features, and LimiGard™ fault protection.

The Limitorque QX design builds on more than 10 years of experience with proven Limitorque MX technology—the first-generation double-sealed electronic valve actuator from Flowserve designed to provide control, ease of use, and accuracy. The QX includes all the user-preferred features of the Limitorque MX in a quarter-turn smart actuator package.
