ロトルクジャパン Company Profile

Rotork has added a compact and robust 90° rotation model to its Skillmatic SI range of self-contained electric hydraulic actuators. This new actuator utilizes a rack and pinion mechanism to deliver a torque of up to 1,000 Nm. The SI range combines the ease of electric operation with the precision of hydraulic control and the reliability of mechanical spring return fail-safe operation. Common applications for the Skillmatic SI actuators include functionally safe emergency shutdown (ESD) inputs and remote-operated shut-off valves (ROSoV). To accommodate various applications, the SI offers a high degree of flexibility in operating speed, ESD options with single or dual inputs, partial stroke testing (PST), and other features. The SI can be provided with hazardous area certification regardless of model and is suitable for use in SIL2 or SIL3 systems. The SI range includes advanced features common to the IQ3 range, such as no need to remove covers during commissioning adjustments (using an intrinsically safe portable Bluetooth configuration tool), performance monitoring, configurable data loggers, multifunctionality, and high availability valve and process data (which can be utilized for asset management and data analysis).

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 newly released a program called "Reliability Services" aimed at improving the reliability of on-site assets. This service provides optimal responses based on the importance of your applications. The Reliability Services adopts a three-tiered approach, allowing you to choose services according to the needs of your assets. Additionally, with your cooperation, Rotolock will accurately identify your unique needs and create a service package tailored to your site. The Reliability Services are divided into three levels: Basic Level: Health Check Standard Level: Planned Maintenance Premium Level: Extended Maintenance Basic (Health Check): Evaluates the condition of on-site assets from the perspective of design specifications and usage. 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.
