AUMA: Fail Safe Actuator

pic AUMA FQMFor applications with significant hazard potential in the oil & gas sector and other industrial markets, fail safe actuators are required. These specialist devices automatically open and close valves in the event of emergency, even with disrupted power supply. Meeting these challenging market requirements, a new AUMA FQM fail safe unit offers an innovative mechanical actuator solution.

Incorporating a patent pending constant force spring motor, the new AUMA fail safe unit mechanically provides the required torque in the event of an emergency. While conventional springs lose 80% of their torque across valve travel, the AUMA solution provides virtually constant torque. Additionally, an overriding gear arrangement ensures that the spring does not move during standard operation. Both these factors contribute to enabling selection of significantly smaller actuator solutions. Premature spring fatigue and excessive torques at the valve are also avoided.

Rotork: IQT Electric Valve Actuator

Rotork IQT electric valve actuatorThe introduction of the new Rotork IQT electric valve actuator brings the advanced functionality and asset management capabilities of Rotork’s 3rd generation intelligent technology to the direct-drive operation of part-turn valves.

Proven in the field by thousands of IQ3 multi-turn actuators, new functionality brought to the compact and robust IQT includes an unrivalled range of advanced data logging and communication capabilities that have been increased in response to the end users’ desire to access more data, both in the field and in the control room.

Diagnostic graphics present a window into the process, showing the valve torque, usage profiles and service logs, facilitating real-time analysis directly at the actuator. The information-rich backlit display is the focus of attention for non-intrusive wireless communication and multi-functional indication, including user-friendly multi-lingual menus for configuration and commissioning.

Flowserve: LPC Compact Pneumatic Actuator

Flowserve Limitorque Pneumatic Compact LPC Scotch Yoke ActuatorFlowserve Corporation announces the launch of the Limitorque Pneumatic Compact (LPC) Scotch yoke actuator. The LPC joins the growing family of technically advanced, fluid-powered actuators under the Limitorque brand that began expanding its portfolio beyond electric actuation earlier this year.

Complementary to the Limitorque Pneumatic Scotch yoke (LPS) model, the LPC applies similar design philosophy as the LPS for long operational life and reliability, but in a more compact, lower-cost package. The LPC has been designed with an industry-leading, 25-year design life, depending on service conditions, proper installation, operation and maintenance. In-field maintenance is required every five years for most applications, or as prescribed in EN 15714 for high-cycle applications.

Curtiss-Wright: Exlar FT45 Actuator

Curtiss-Wright Exlar FT45 ActuatorCurtiss-Wright Corporation announced the expansion of its Exlar FT Series™ universal electric rod style linear actuator product line with the release of the FT45 model.

The FT Series roller screw driven actuators offer high thrust, high speed, and high robustness in a compact form factor, making them an ideal alternative to hydraulic cylinders. With continuous force rating to 40,000 lbf (178 kN), speed to 60 in/sec (1,500mm/sec) and stroke lengths from 6 inches (150mm) to 8 feet (2,400mm) the FT Series can be applied across a wide range of linear motion applications.

The new FT45 has a continuous force rating of 10,000 lbf (44.5 kN), filling the gap between the existing FT35 and FT60 models.
