Targeted at petroleum refining, chemical, and related industries, the 6000 Series offers significantly enhanced control performance, space-saving design, and improved maintainability.
Azbil Corporation has announced that it will begin sales of the 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, installation space requirements, and spare parts stocks, as well as enhancing maintainability.
A control valve is an essential piece of equipment for fluid flow control in production processes. High control performance and long-term stability are particularly demanded of the control valves used for process automation in the petroleum, petrochemical, and related industries. In addition, they are required to conform to international standards to ensure competitiveness in global markets. Moreover, because of the impact of work-style reforms and structural changes in the working population on production sites, customers 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.
Key Features
Using high-precision simulations employing CFD analysis, the internal structure has been designed to optimize valve performance. As a result, the representative index for valve performance, the rated CV value, was improved by 129 percent compared to the company’s single-seat valves and by 125 percent compared to the cage valves. Additionally, the actual performance of valve prototypes was evaluated using specialized flow-test equipment—conforming to 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.
The valve height has been reduced by as much as 40 percent while still offering flow characteristics that are either equivalent to or better than previous models. Because a single 6000 Series unit enables stable control of a wide range of flow rates, equipment costs and required space can be reduced. Despite its compact dimensions, the 6000 Series delivers excellent shutoff performance, enabling significant improvements in operational efficiency, including reduced air consumption and greater convenience for on-site work.
The design of the 6000 Series places emphasis on maintainability. For example, it makes use of common components for a range of sizes and features a structure that requires no special tools for maintenance. As a result, maintenance work can be carried out more efficiently, and parts management has been simplified, thus helping to reduce the workload for customers and lowering operating costs over the long term.
As the next-generation standard platform for Azbil’s process automation control valves, the 6000 Series is highly proficient. It will continue to evolve, leveraging Azbil’s long-standing expertise in valve design to meet the needs of a wide variety of industries while pursuing market expansion. Furthermore, in the medium-term management plan formulated in May 2025, Azbil set forth the goal of “Create New Automation” as a growth strategy for its Advanced Automation business.
As part of this strategy, Azbil plans to integrate technologies related to control valves (CV)—including control valves, valve positioners, maintenance services, and valve diagnostic services—into a comprehensive offering called the “CV Total Solution.” By doing so, the company aims to provide added value through the synergistic effects of these elements, thereby contributing to improved operational efficiency for customers’ plants. The newly launched 6000 Series serves as a significant product within the CV Total Solution.
Guided by the Azbil Group philosophy of “human-centered automation,” the company strives to supply products and services that contribute to solving societal issues as well as benefiting the global environment, with the aim of making contributions that lead “in series” to a sustainable society and to achieving sustainable growth.
