Rotork CQ Compact actuators – power and performance where space is limited

The launch of the Rotork CQ Compact introduces a range of fully concentric, balanced design pneumatic and hydraulic valve actuators that deliver a reliable and efficient self-contained solution for applications demanding functional integrity and safety where space is limited.

In addition to providing reduced dimensions when compared with conventional scotch-yoke actuators, the CQ’s symmetric design also presents a perfect weight balance on the valve, enabling increased efficiency for assembly and disassembly. The totally enclosed, rugged CQ weatherproof housing contains a helical mechanism which transforms linear piston motion into 90º (+/-5º) rotation for the operation of quarter-turn valves. As an option, rotation can be increased to 180º. Complete customisation of the torque profile is available to suit individual valve requirements.

The CQ range features a choice of cylinder sizes and different actuator builds for many diverse applications. In all cases the CQ design incorporates the removable valve adaptation within the overall dimensions for maximum compactness and actuators can be easily and safely disassembled to access internal parts for field maintenance. Internal coatings provide enhanced corrosion protection for long term reliability. External epoxy finishes and a wide choice of seal materials can be specified to meet industry and customer requirements.

CQ Compact actuators are available for single or double-acting operation with output torques up to 600,000 Nm. Pneumatic operation is available using instrument air, nitrogen or clean natural gas at 12 barg pressure, whilst 210 barg is recommended for hydraulic operation. Environmental and hazardous area certifications include IP66M/IP68M, PED, ATEX, IECEx and GOST. The actuators are also suitable for SIL3 safety related duty.

The standard operating temperature range is -30ºC to +100ºC providing suitability for applications in harsh and challenging environments, with an optional low temperature limit of -60ºC.

Rotork introduces SMART-LOC™ - a modular solution for pneumatic actuator control

Rotork Modular Actuator.jpgRotork Midland introduces SMART-LOC, a new high integrity modular concept for pneumatic actuator control assemblies. Constructed in 316L stainless steel, the SMART-LOC system is particularly suitable for the control and sequencing of process valve actuators in oil and gas applications.

Compared to traditional fabricated panel mounted assemblies SMART-LOC offers a lighter, stronger and more compact alternative, together with significant capital and operating cost savings. Complex, labour intensive arrangements using panels, pipes and additional fittings are eliminated and replaced with a fully assembled and tested interface block, ready to be fitted directly to the actuator. Delivering best in class flow characteristics, the units will interface with all types of pneumatic actuators.

A range of field proven components – valves (spool, poppet or direct mounting) and filter regulators – connected in series on the interface, are tailored to meet the requirements of individual projects, ranging from standard shut-off circuits to intricate control circuits. The unique SMART-LOC clamping system for individual components incorporates static O-rings for higher integrity and long term reliability. No design work is required from the contractor and all components are kept in stock, resulting in very short lead times. With ATEX approval, SMART-LOC components are suitable for hazardous areas and industrial use.

The integral SMART-LOC clamping system also simplifies field maintenance, enabling individual components to be simply and swiftly unclamped and replaced.

SMART-LOC is designed with the benefit of more than 50 years’ experience in the manufacture of stainless steel pneumatic components, during which time Rotork Midland has developed a range of field proven specialist products that are renowned for their performance and reliability.

Rotork third generation Skilmatic delivers Smarter Failsafe Actuation

Rotork- Failsafe Actuator.jpgThe Rotork Skilmatic SI self-contained electro-hydraulic valve actuator combines all-electric simplicity with the precision of hydraulic actuation and the reliability of mechanical failsafe operation. Typical applications for Skilmatic actuators include functional safety related Emergency Shutdown (ESD) and Remotely Operated Shutoff Valve (ROSoV) duties.

Skilmatic’s advanced control and monitoring system has now been further developed with the introduction of the 3rd Generation, incorporating proven Rotork IQ3 intelligent electric actuator technology. Communication and data logging capabilities have been increased in response to end users’ desire to access more valve related data, both in the field and in the control room.

The 3rd Generation of the SI actuator will consist of four models with multiple actuator sizes known as SI³-1, SI³-2, SI³-3 and SI³-4, enabling Rotork to offer quarter-turn failsafe actuation from 65Nm up to 600,000Nm for functional safety applications. As part of the development Rotork has enhanced the range by introducing the new SI³-3 standard range of spring return actuators with a torque range of 2,000Nm to 20,000Nm. This new range offers a wide choice of operating speeds, additional ESD options with single or dual inputs and enhancements to partial stroking to meet a wide range of applications.

Skilmatic SI 3rd Generation actuators combine established features including non-intrusive setting, performance monitoring and configurable data logging with an extended torque output range, increased functionality and enhanced availability of valve and process data for asset management and data analysis, displayed in a new, large and information-rich format.

Robustly constructed for challenging environments, SI 3rd Generation actuators deliver a highly reliable means of valve management and positioning a valve to a safe condition. Safe valve positioning is selectable for failsafe to open, failsafe to close or lock in position on either loss of power or a range of programmable ESD signal options.

The SI 3rd Generation control module facilitates simple, safe and swift non-intrusive commissioning by means of an intrinsically safe hand held setting tool with infra-red and Bluetooth™ interfaces. Settings including internal hydraulic pressure, position, limits, control, alarm and indication functions can be accessed and adjusted using user-friendly Rotork ‘point and shoot’ menus. Actuator status, control and alarm icons are provided on an advanced new dual-stack toughened glass illuminated display which also gives access to real-time information such as pressure, diagnostics and help screens.
