Rotork's electric actuators control the sluice gates at a sewage treatment plant (STP) in Australia. The third-generation IQ multi-turn electric actuators are installed on eight sluice gates, regulating the flow of sewage entering the sewage treatment plant in Murrumba Downs, a suburb in Queensland, Australia. The end user, Unitywater, chose Rotork products to automate the opening and closing of the sluice gates. Previously, operators had to use stairs to approach the gates and operate them manually. To enhance safety on site, several IQ3 actuators installed at the Murrumba Downs site were equipped with RHS, allowing workers to operate the valves safely from the field. The RHS features the same display and control interface as the IQ3, enabling operation and configuration from up to 100 meters away from the actuator. It can supply 24VDC power from the connected actuator, eliminating the need for an auxiliary power source. Additionally, the RHS can be mounted on columns or walls.

Rotork recently installed the CVL linear actuator for control valves at the Didcot B power station (a power plant supplying electricity to the National Grid) and conducted commissioning adjustments. The Rotork CVL1500 and CVL5000 actuators control the supply of injection water used as emergency cooling water when the steam turbine trips. The CVL actuators were installed as part of a project to improve equipment reliability and address the aging of older plants. The CVL actuators are linear models of the electric actuators for process control, known as CVA. This CVL model operates on single-phase or DC power, providing very precise and responsive continuous adjustments of the control valve. By replacing existing actuators with the CVL, reliability has improved, and maintenance costs have been reduced. This unit enables highly accurate flow control with a resolution of over 0.1% and can also perform repeatable position control using a 4-20mA signal. The thrust of the CVL ranges from 890 N to 22,241 N (200 to 5,000 lbf).

The Rotork electric multi-turn actuator IQ3 has been installed at the world's largest (planned) waste incineration power plant located in Bao'an District, Shenzhen, China. This actuator is intended to be used at the aforementioned power plant, which is scheduled to start operations in 2020, for operating gate valves, globe valves, butterfly valves, ball valves, and even dampers. Additionally, it has been installed not only in process plants such as waste heat boilers but also in gas control, water treatment, and public pipeline systems. The latest IQ actuators feature an advanced dual-stack display with a configurable data logger and a Bluetooth-enabled setting device, reflecting technical improvements. The actuator's settings and commissioning adjustments can be performed using the Rotork Bluetooth setting device, and data can also be transferred to a PC for analysis (using diagnostic software called Rotork Insight 2). The data logger used in the IQ collects and stores various data, including torque distribution, number of starts, and logs of vibrations and temperatures. All data is stored in non-volatile EEPROM.

To provide fresh drinking water to regional communities in Germany, Rotork's electric actuators and pneumatic actuators have been installed. 39 GT (pneumatic piston actuators) and 13 CK (modular electric actuators) have been supplied to Stadtwerke Lohr Am Main and are being used in two municipal water treatment facilities that supply water to the town of Lohr am Main and its surrounding areas in Bavaria. The GT and CK were installed in separate plants. At these two sites, water is sourced from six springs and two deep wells, and processed at seven water treatment facilities. The GT and CK are installed on 2 to 12-inch butterfly valves and gate valves, driving the shut-off valves in the water channels of the plants, facilitating filtration, storage, and supply. The treated water is stored in underground reservoirs and supplied through a 180 km pipeline network. Rotork's open network and consulting by specialized personnel were key factors in reaching the contract. Additionally, the functionality, reliability, and durability of the actuators, as well as the modular structure of the CK, were also considered important factors.

Rotork's electric actuators (IQ3) and fluid power actuators (CP and GP) have been installed in Brazil's new floating production storage and offloading unit (FPSO). The Rotork CP range consists of versatile and modular pneumatic actuators that employ a Scotch yoke design (available in double-acting and spring-return types). The CP actuators are compact and efficient, capable of generating torque up to 4,500 Nm (39,800 lbf.ft) even in low-temperature environments. The GP is a Scotch yoke actuator for 90° rotating valves, suitable for on/off and modulating applications. The GP (available in double-acting and spring-return types) can produce output torque up to 600,000 Nm (5,000,000 lbf.ft) and can be used in SIL2 and SIL3 systems. The IQ3 electric actuator can be used for on/off or inching applications with a starting frequency of up to 60 cycles per minute, and its direct drive output torque ranges from 14 Nm (10 lbf.ft) to 3,000 Nm (2,200 lbf.ft).

Rotolock provided CK modular electric actuators to a wastewater treatment plant in Turkey, offering a solution that is environmentally friendly and safe. The CK actuators used in this project are waterproof and suitable for all valves in non-hazardous areas. They can also operate under load conditions such as high temperatures and strong vibrations.

Rotolock has installed over 150 RC200 pneumatic actuators in the fire dampers' valves of the Turkish subway. (Note: Fire dampers are safety products installed inside railway tunnels to prevent the spread of flames and smoke, closing during a fire to prevent flames and smoke from reaching the railway tunnel.) The RC200 is a compact pneumatic actuator equipped with a Scotch-Yoke mechanism, performing ESD or isolation functions. It was chosen for its fast operating speed and long-term use with minimal maintenance, utilizing a spring-return design. The actuators in the RC range can operate normally even in high-temperature environments ranging from 0 °C to +150 °C. In this case, a high-temperature model capable of withstanding 250 °C for 2 hours and an additional hour at 400 °C was selected. The RC pneumatic actuators operate at such high temperatures without affecting the exterior fireproof coating. This actuator has obtained ATEX 2014/34/EU certification.

The fireboats used by the New York City Fire Department (FDNY) Marine Firefighting Division employ Rotork's IQ range 90° rotation electric actuators to maintain the city's safety. The 90° rotation IQ actuators are used on two fireboats, "Firefighter 2" and "Firefighter 343." The IQ plays a crucial role in controlling the water flow to the deck's firefighting water spray nozzles, which is essential during emergencies. New York is one of the busiest port cities in the world, with a coastline extending 560 miles. For many years, the FDNY has addressed firefighting-related incidents on land and at sea using fireboats. The fireboats draw water from the river, and the actuators control the flow of water supplied to the firefighting water spray nozzles, allowing the fireboats to access an unlimited water supply even in emergencies. It is very important to constantly manage the water flow supplied to the spray nozzles. The IQ actuators were installed due to the failure of existing electric actuators. The IQ actuators are not only waterproof but also feature a double seal structure with an IP66/68 rating (withstanding depths of 7 meters for 72 hours).

In a glass factory in Turkey, the installation of Rotork's electric actuators has achieved improved combustion efficiency and reduced emissions. Thirty-three ROMpak electric actuators have been installed at a glass factory in the Mersin region of southern Turkey (operated by Şişecam). The ROMpak actuators have been installed to replace the existing actuators for operating butterfly valves, controlling the flow of hot air at the center of the glass manufacturing process. For complete and efficient combustion, it is necessary to control the air-fuel ratio in the furnace to be leaner than the theoretical air-fuel ratio, allowing for dilute combustion. Complete combustion leads to reduced running costs and minimizes fuel waste, contributing to the reduction of emissions and environmental pollutants. The control provided by Rotork's ROMpak supports the optimization of essential processes. The ROMpak actuators reliably and quietly control small ball valves and butterfly valves. ROMpak is equipped with a continuous opening degree indicator that can be used at all times and in ambient temperatures up to +70°C. The waterproof and dustproof rating of ROMpak is IP68 (for 100 hours at a depth of 10 meters).

Visual inspection. Standard (Planned Maintenance): In addition to the "Basic" service, workers will conduct actual inspections. Corrective actions will be taken as desired, and consumable parts will be replaced as necessary. Premium (Extended Maintenance): In addition to all services in the Basic and Standard levels, inspections of parts based on condition (excluding some parts) and data reporting through Advanced Asset Management (iAM) will also be conducted.

A Rotork IQ actuator has been installed at the sewage treatment plant's pump station in Hong Kong. The IQ actuator was installed to electrify existing manual valves and is equipped with intelligent features. Approximately 50 actuators have been installed for valve operation. The IQ actuators, equipped with IB multi-turn gearboxes, are used for site penstocks and gate valves, while the IQM actuators, which are the modulating model of IQ3, are installed in balancing tanks and gas systems. The IQM incorporates a solid-state reversible starter, allowing for quicker responses to changes in position signals. Additionally, this solid-state starter adds a "brake" function to the electric motor, optimizing position control. The IQ intelligent actuators have high sealing performance against external environments, featuring a double-sealed housing (IP66 or 68), making them ideal for pump station applications. The IQ actuators are characterized by high-reliability absolute encoders and an intuitive UI, making them the selected actuators for highly automated valve operations.

Rotolock has released the SPI Smart Position Indicator, making significant improvements in robustness, reliability, and accuracy. By installing the SPI, it is possible to monitor any valve within the refining plant from the control center, leading to improved operational control accuracy. The SPI features a large digital display, allowing for the verification of valve opening on-site. It also includes one to two built-in switches or sensors for remote display. Furthermore, it is completely sealed in an aluminum housing, accurately outputting the valve position signal. For large valves with a gearbox, the installation position of the SPI is at the input flange of the gearbox. For small valves, it can be directly mounted on the valve, and for stem rising valves, an optional thrust base is also available. The SPI uses the same ISO5210 valve mounting as electric actuators, which is more robust than traditional arm types. The SPI has an environmental resistance rating equivalent to IP67, and as a sister version, we offer an IECEx/ATEX explosion-proof unit for hazardous locations.

The Rotork master station can operate up to 240 actuators across three different field networks. This allows for the optimal use of networks even when multiple plants are located in separate areas. The new master station has also been made compatible with Modbus RTU networks, enabling connections to third-party products. The network of the master station can be made redundant through hot standby, so if one unit encounters an error, control can continue with another unit. All network communications are fault-tolerant, allowing for the continued operation of the plant even in the event of a failure. During the installation of the master station, twisted pair shielded cables are used, making it cost-effective and simple. Additionally, it can control devices located up to 20 km away without the need for external repeaters, further saving on labor costs, installation expenses, and commissioning adjustment costs. Rotork's master station can be easily integrated into existing equipment and can control all types of drive devices, including those from other manufacturers.

The Rotork IQ Intelligent Valve Actuator is recognized as a robust and easy-to-operate product equipped with advanced technology. With the addition of a custom-made plug-and-socket connection as an option, the quality of the IQ has further improved. The newly adopted plug-and-socket connections in the IQ3 (multi-turn: single-phase, three-phase), IQT3 (90-degree rotation: single-phase, three-phase, DC), and many pressure-resistant explosion-proof actuators (models compliant with international standards such as ATEX, IECEx, CSA, CSAus, etc.) feature modular coupling parts, allowing for quick attachment and detachment. The terminal cover of the plug-and-socket section ensures the double seal of the actuator body and fully maintains IP68 waterproofing (up to 20 meters deep for 10 days). There are industries that prefer plug-and-socket connections because they allow for quick and easy wiring in the field, as well as rapid removal or replacement when maintenance is needed. By adopting this type of connection, the IQ actuator's advanced and user-friendly design has gained additional flexibility.
