• Proactive maintenance with IoT insights

Best-in-class actuation for your demanding applications The Limitorque portfolio of valve automation products from Flowserve has enabled companies around the world to address their most-challenging flow control issues. The Limitorque brand has evolved since its strategic introduction of a torque-limiting design that changed the industry 80 years ago. Today, Limitorque smart actuators deliver:
• Significant total lifecycle cost savings
• Greater operating efficiencies and process optimization
• Increased visibility into equipment conditions to enhance performance and avoid unplanned downtime

Limitorque MX and QX Series B Smart Electric Actuators Electric actuators must perform reliably in severe environments and harsh conditions. Any failure can compromise valve performance, plant productivity and employee safety. That’s why Flowserve engineered the Limitorque MXb and QXb electric actuators for dependable performance across a broad range of tough applications, including:
• Oil and gas
• Petrochemical
• Commercial power
• Chemical
• Water
• Wastewater
• General industries

Ease of use
• Commissioning is 50% faster owing to a simplified menu and navigation, without the need for special tools.
• The high-resolution control panel display:
– Delivers instant and up-to-the-minute actuator status and valve position
– Shows clear historical and real-time graphs for critical process information such as torque, vibration and temperature profiles
– Automatically adjusts brightness to enable visibility in all lighting conditions
– Includes multiple languages for ease of use
– Rotates to accommodate equipment orientations and installations

Reduced costs
• Backward compatibility enables cost-effective upgrading of existing MX and QX models to the advanced B series.
• Thermal resistance increases mean time between failure (MTBF).
• Oil bath lubrication extends the actuator life, enables storage and mounting in any orientation while maintaining full coverage, and eliminates the need for regular maintenance.

The MX electronic actuator is the platform for current and future network developments including Modbus DDC, Foundation Fieldbus H1, Profibus DP_V1, Profibus_ PA, and DeviceNet. Distinguishing itself from the competition, the MX actuator features an absolute encoder which doesn’t require battery back-up and is designed with B.I.S.T. (Built In Self Test) capability for self-diagnosis. Additional features include LimiGard circuitry, which safeguards the actuator from spurious electro-magnetic interference, MX Quik, providing an uninterrupted power transfer option during main power losses, and Limitorque’s namesake feature – torque sensing.

The MX multi-turn electronic actuator can provide torque output of up to 1700 ft. lbs and is available in a wide variety of configurations to accommodate various applications and valve designs. For torque-only applications, the MX can be directly coupled with valves. Thrust applications rely on a separate thrust base that is available.  The MX can additionally be coupled to a PT or HBC worm gear reducer for operation on part-turn valves such as butterflies, balls, plugs, and dampers. For rising stem valve applications the MX can be coupled with a B320 or MT bevel gear reducer.

The Flowserve Limitorque MX has been selected as the electronic actuator of choice by a variety of prominent companies such as The Department of Environmental Protection of the City of New York, Saudi Aramco, Chevron, Calpine, Alyeska Pipeline, and SINOPEC.  The MX actuator provides the user with predictable, reliable and safe operation for years to come, in the most rigorous applications and extreme environments. Whatever your valve automation needs, look no farther than Limitorque’s multi-turn MX smart electronic actuator.
