Azbil Corporation has begun sales of its 6000 Series of control valves. Conforming to the IEC 60534 international standard, the 6000 Series represents a core product for the petroleum refining, petrochemical, chemical, and related industrial markets. With an optimal design based on CFD analysis, it significantly enhances control performance while contributing to overall productivity improvements throughout a plant’s lifecycle. This is achieved not only through improved control accuracy, but also by reducing equipment costs, reducing install space requirements, reducing spare parts stocks, and enhanced maintainability.
A control valve is an essential piece of equipment for fluid flow control in production processes. Especially high control performance and long-term stability are demanded of the control valves used for process automation in the petroleum, petrochemical, and related industries. In addition, it is required that they conform to international standards to ensure competitiveness in global markets. Moreover, because of the impact on production sites of work-style reforms and structural changes in the working population, customers today increasingly expect control valves and other production equipment to contribute to improving productivity throughout a plant’s lifecycle. It was in response to these market needs that the 6000 Series was developed.
Using high-precision simulations employing CFD analysis, it designed the internal structure to optimize valve performance. As a result, the representative index for valve performance, the rated Cv value, was improved by 129% compared to its single-seat valves and by 125% compared to its cage valves. Additionally, the actual performance of valve prototypes was evaluated using specialized flow-test equipment, which conforms with international standards, at Azbil Kyoto Co., Ltd., a member of the azbil Group. This process has resulted in significantly enhanced reliability with improved accuracy and reproducibility of measurement results. Furthermore, the 6000 Series contributes to reducing energy losses by facilitating precise valve selection.
