Exhibits high airtightness and valve seat sealing performance! Excellent in corrosion resistance, chemical resistance, and cleanability.

A diaphragm valve is a type of valve that has a structure for opening and closing the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear-type diaphragm valve: Type 400" is the basic form of a diaphragm valve that has a weir in the flow path. The fluid passage section is streamlined and has no pocket areas, which minimizes liquid accumulation and provides self-cleaning properties. Due to the valve's structure, it exhibits high airtightness and seat sealing performance. There is a wide variety of materials available for the body and diaphragm, allowing it to accommodate a broad range of fluids. ▼Applicable fields: Chemicals, environmental and water treatment, steel, shipping, pharmaceuticals, food, semiconductors, power generation, etc. *For more details, please refer to the catalog (P6–P14) or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

The flow path is close to straight, with a structure that has low pressure loss and minimal liquid accumulation! It is suitable for fluids containing sludge, suspended solids, and more!

A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Straight Type Diaphragm Valve: 500 Series" features a flow path that is nearly linear (straight), resulting in a structure with minimal pressure loss and liquid accumulation. It is suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. ▼ Application Fields: Water treatment plants, final treatment facilities, etc. *For more details, please refer to the PDF materials or feel free to contact us.

[Speaker] Mr. Manabu Kamitani, Manager, Performance Unit, Arthur D. Little Japan K.K. [Key Lecture Content] In recent years, both quantum technology and AI have seen technological development and investment at the national level, not just by companies, in various countries. While private enterprises are advancing the verification of the potential and promise of both quantum and AI technologies, the societal penetration of these technologies differs due to the uncertainty of their evolution. This has led to a demand for advanced technological intelligence capabilities that balance the maturity of the technology with expectations for its application in business development and internal implementation based on cutting-edge technologies. This lecture will multifacetedly examine the key points of how to utilize developing advanced technologies, taking into account the current understanding and future direction of quantum technology and AI. [Lecture Items] 1. Current status of the utilization of quantum technology and AI 2. Future development directions of quantum technology and AI and challenges toward realization 3. Considerations for business development and planning for advanced technologies based on the current status and challenges 4. Summary of today's discussion 5. Q&A / Business card exchange

[Speaker] Takayuki Furuta, Director of the Future Robot Technology Research Center (fuRo), Executive Director of Chiba Institute of Technology [Key Lecture Content] The true value of robotic technology lies in its ability to directly impact the physical world, creating tangible value for society, from economic activities to people's daily lives. This lecture will focus on the evolution of robotic technology as a core system that connects cyberspace and the real world, introducing development examples of AI-equipped mobility. Furthermore, while considering the latest trends in robotic technology being utilized in real society, we will explore the future direction and potential of technological development.

[Speaker] Tetsuji Narita, President of NRT Energy Bridge Co., Ltd. [Key Lecture Content] Due to the rapid expansion of AI data centers, the power system is transitioning from "ensuring quantity" to "simultaneous design of reliability, environmental value, and construction period." While the government is taking steps to ensure system capacity in collaboration with watt-bit and in GX strategy regions, on-site, different entities such as DC operators, retailers, power generation and storage, local governments, and transmission companies tend to operate in different languages. This lecture will organize the current state of the system from PPA to practical design of power source portfolios, providing a checklist for each stakeholder and a common language to "operate on the same schedule." [Lecture Items] 1. Overall Overview: Structural organization of how AI DC has become a "design variable" in the power system 2. Current state of watt-bit collaboration and connection discipline 3. GX strategy regions (DC aggregation type): Issues in industrial cluster design 4. Practical design of PPA and power source portfolio 5. Preparation for environmental value and 24/7 CFE 6. Summary: Stakeholder-specific checklist and common schedule 7. Q&A / Business card exchange

[Speaker] Kazuhiro Kaiho, Manager, Environmental, Energy, and Resource Strategy Group, Research and Consulting Division, Japan Research Institute, Ltd. [Key Lecture Content] Decarbonization of automobiles is entering a phase where EVs, hydrogen, and RNG are utilized according to the industrial structure of countries and regions, energy resources such as renewable energy and biomass, and infrastructure constraints, rather than being solely focused on EVs. This presentation will compare the U.S. tax credits, LCFS, and RFS; China's NEV promotion policies and hydrogen demonstrations; and Europe's RED III and AFIR, organizing which fuels each region is aiming to expand for which applications. It will highlight different winning strategies for passenger and commercial vehicles and provide insights for Japanese companies. [Lecture Items] 1. Why is it important to view "automotive fuel policy" through regional comparisons now? 2. United States: Expanding RNG, hydrogen, and low-carbon fuels through market incentives. 3. China: A dual-front strategy focusing on EVs while nurturing hydrogen for commercial vehicles. 4. Europe: Advancing EVs, hydrogen, and renewable gas through regulatory leadership. 5.
