Rotork launches 3rd generation IQT intelligent part-turn valve actuator

Rotork IQT intelligent actuator.jpgThe 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. Local position indication, valve and actuator status, asset management and diagnostic operating information is available to download and can be viewed directly at the actuator on the large LCD display. The display provides real-time status data, positional and warning icon information; actuator setup and operating menus along with detailed diagnostic and operational data screens are clearly displayed in dot matrix format.

Using the Rotork Bluetooth® Setting Tool Pro, commissioning and configuring the actuator is faster and simpler than ever. The setting tool can also be used to securely transfer data from the actuators to a PC for analysis using Rotork Insight2 diagnostic software. Insight2 can further streamline actuator set up by pre-defining complete sets of instructions and settings. Each collection of settings can be saved as a ‘mission data set’ and quickly applied to multiple actuators requiring the same configuration.

Valve maintenance requirements can be identified and anticipated, eliminating unplanned interruptions to the process or over-cautious planned maintenance outages. The actuator's powerful datalogger provides comprehensive data capture for planned maintenance and troubleshooting. Data includes valve torque profiles, operational start profiles, vibration and temperature trend logs and an event log. Specific asset management information includes running time, average torque and number of starts. Service or maintenance alarms are selectable from configurable menus including open and close torque levels, total starts and vibration levels.

Torque sensing is reliable and accurate over the life of the actuator. Similarly, reliable valve positioning is critical. A patented absolute encoder with only one moving part tracks valve position without the requirement for a battery even when there is loss of power. In addition, as all configuration and datalogger data is stored in a non-volatile EEPROM memory, all settings are retained. If an actuator is manually operated during a power outage, the local display and remote indication is kept updated by the use of a battery which also facilitates data logging and power-off commissioning.

The IQT’s double-sealed IP68 watertight and temporarily submersible enclosure is universal to all Rotork actuators, including those with explosion proof certification. It permanently protects internal electrics from the ambient environment, even during site wiring with the terminal housing cover removed. The double-sealed design, in which the terminal housing is separately O-ring sealed from the rest of the actuator, has been a standard feature on Rotork electric actuators for over forty years. It is proven to increase long term reliability and durability in the harshest of climates. A plug and socket connector option is available which also retains the double-sealed design.

On the actuator’s compact and robust enclosure, local Open/Close and Local/Stop/Remote selectors are coupled magnetically to internal switches without penetrating the actuator body, further enhancing non-intrusive environmental protection. Emergency handwheel operation with motor preference is provided as standard.

IQT actuators are suitable for three phase, single phase or DC power supplies, with a torque output range of 50 to 2000Nm available for isolating, regulating and modulating duties. The motor always runs in the correct direction, irrespective of supply type and connection. In addition, the output speed can be non-intrusively adjusted over a 4:1 range without affecting the output torque. All valve interface bases conform to ISO5211 or MSS SP 101 and are fitted with removable couplings.

Hazardous area actuators are fully approved to the latest ATEX standards. Network connectivity options include Foundation Fieldbus®, Profibus®, HART® and DeviceNet® open systems, as well as Rotork's own dedicated Pakscan wired or wireless systems.

Emerson’s condition monitoring system expands protection to more field assets

CSI3000.jpgEmerson Process Management has introduced the CSI 3000 Machinery Health Monitor, a compact protection system for a wide range of machinery such as pumps, compressors, centrifuges, blowers, and generators. The CSI 3000 delivers protection data in situations where a standard rack-based system simply will not fit or is not a cost-effective approach. Easy assembly and user-friendly, customizable setup means the CSI 3000 has a short path out of the box to improving availability and ensuring safety of rotating assets.

The CSI 3000 measures shaft vibration, bearing vibration, position, speed and generates key signals. The system provides the user with alarm outputs for each channel and does not require additional signal converters for shaft vibration and displacement measurements.

“Emerson offers a complete line of protection monitors – from the rack-mounted CSI 6500 online monitoring system and the basic CSI 9360 Vibration/Position Transmitter, to the CSI 6300 SIS that guards against overspeed conditions,” said Björn Müller, Emerson’s product manager of online sensors. “This is another example of how we are delivering capabilities that bring stability to our user’s operations through services and technologies that reduce downtime and improve availability.”

YTC positioners lead the way in tough applications

YTC positioners.jpgProcess industries often depend on high performance valve actuation in harsh environments. Despite the difficult surroundings, process plants demand the latest technology, such as smart positioners, which allow technicians to use auto-calibration and simple diagnostics to commission and monitor their entire system at the push of a button. In many cases, the valve, actuator and smart positioner package is exposed to extreme temperatures, dirty conditions and other challenges such as high vibration.

Most instrumentation positioners would fail quickly when subjected to these harsh environments. For example, smart positioners require internal electrical components which are extremely vulnerable at high temperatures and may prematurely fail when exposed. Young Tech Company (YTC) has developed two smart positioner products to thrive under these conditions which have paved the way to expansion and growth in tough process control applications.

Remote sensing unit positioners:

The YT-3301 introduced the concept of isolating and detaching the sensing feedback portion of the positioner from the main control housing. The sensing unit accurately detects the position of the valve stem and provides a feedback signal to the main housing. This dual unit design allows the operator to locate the precision electronics elements at a considerable distance from the valve environment, providing the best of both worlds – precision engagement at the point of valve movement and a clean, dry and ambient temperature for the electronics. This also facilitates mounting multiple control housings in close proximity for convenient and time saving monitoring and adjustment of valves in the plant.

Triple module remote positioners:

Remotely mounting the sensing unit provides dramatically improved reliability and performance, but at longer distances between the sensing unit and the control housing pneumatic signal loss may occur. In extreme situations this could lead to hunting and oscillation of the electronics and reduced valve and actuator positional stability.

To assure superior performance in these difficult applications, YTC has developed the YT-3302 Positioner. With this product a third module, housing the driving components of the pilot valve and torque motor assembly, is mounted at an intermediate location between the remote sensing unit and the main control unit. Accordingly, the three modules are the sensing unit, driving unit and control housing. As the sensing unit contains the most robust components and the control the most sensitive, this configuration delivers higher performance with dramatically increased positional accuracy.


Added benefits include the ease of maintenance for each of the modules and the ability to gang mount modules at convenient locations. Standardisation of modules and components also facilitates spare part simplification and inventory cost reduction.
