Limitorque actuators have been making control easier at the field-device level for over 80 years.Limitorque actuators drive multi-turn and quarter-turn industrial valves, day after day, year after year, using conventional and advanced technologies to reduce costs and increase operating efficiencies for customers. |
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 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 MX in a quarter-turn smart actuator package. |

Limitorque MX Electronic Valve ActuatorThe MX is Flowserve Limitorque's product entry in the non-intrusive, double-sealed, smart electronic actuator marketplace. The MX has been readily accepted into all major market segments, including Power Generation, Petro-chemical, and Water/Waste Water Treatment. The MX is the platform for current and future network developments, including Modbus DDC, Foundation Fieldbus H1, Profibus DP_V1, Profibus_ PA and is now available with DeviceNet. The MX can easily be distinguished from other smart valve actuators with its absolute encoder that doesn't require battery back-up and features B.I.S.T.(Built In Self Test)capability for self-diagnosis. Additional features include easy configuration in nine languages, LimiGard circuitry, which safeguards the actuator from spurious electro-magnetic interference. The MX can provide torque output of up to 1700 ft.lbs. Several enhancements have been made to the MX, including replacement of an outdated perforated through hole PCB controls set with SMT (Surface Mount Technology) controls in 2003. An improved ACP (Actuator Control Panel) with recessed knobs and solid state Hall-effect devices in lieu of reed switches has replaced the original controls cover.

L120 Multi-Turn Electric ActuatorLimitorque's L120 Series multi-turn actuators have a solid record of making valve control easier in a wide variety of demanding applications. Low maintenance requirements make the L120 series ideally suited for water and waste treatment applications. Limitorque's L120 actuators are ideal for valves requiring rotary or linear movement. With nine unit sizes, L120 electric actuators make it easy to meet or exceed your requirements for positive, dependable, valve actuation. Whether used with gate and globe valves, penstocks, or sluice gates, versatile L120 Series actuators operate without modification in any rising or non-rising stem application for linear-action valves. When combined with a Limitorque's PT or HBC worm gear operators, L120 actuators can also be used to control butterfly, ball, and plug valves, as well as damper drives, flop gates, or any other device which requires rotary movement.
