【New Product Exhibition Planned!】Announcement of Participation in the 26th Interphex Japan Exhibition

Are you having trouble with "contamination control"? We can eliminate liquid pooling and ensure that cleaning and sterilization can be carried out easily and reliably!

■NDV Dead Space Countermeasure Products These are products designed with a compact structure that eliminates dead spaces (such as pockets and liquid traps) in the valve body. They can be used as "contamination countermeasures" in pharmaceuticals, food, and bioprocesses. 【Are you facing any of these issues?】 ☑ Fluid enters the gaps inside the valve during fluid passage or when closing the valve... ☑ Large dead legs in piping cause issues like liquid traps and ineffective steam sterilization... ☑ You want to review complex piping layouts to eliminate fluid contamination risks... 【Features】 ● Sampling Valve Type P: - Enables fluid sampling without dead space! ● Three-Way Valve Type K: - Allows switching and mixing of flow paths with one body, without dead space! ● Tank Bottom Valve Type T: - A valve specifically for tank bottoms that achieves high stirring efficiency and eliminates residual discharge! ● Self-Drain Type F: - A valve that further enhances the effect of preventing liquid traps! ■ This product will be exhibited at the "26th Interphex Japan." *For more details, please refer to the catalog or feel free to contact us.

• Unit and other construction

Easy with 90-degree operation! Prevents over-tightening and damage! "I'm worried if it's securely tightened..." We solve this kind of concern.

The "BQL400NB model" is a rapid opening and closing type handle diaphragm valve from BioClean. While the standard handle version requires about 5 turns of operation (for DN50), the rapid opening and closing handle allows for a very simple operation of just "opening and closing by 90 degrees." The valve's open and closed status can be clearly seen from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable closing performance of the 90-degree rotating lever handle. 【We solve the following problems!】 ■ Excessive opening and closing torque → Reduction is possible, greatly contributing to labor savings. ■ Want to check the opening and closing status from a distance → The valve's open and closed status can be clearly seen from a distance based on the handle position. ■ Damage caused by over-tightening the valve → Only the minimum necessary operation is required. This prevents damage and extends lifespan. *For more details, please refer to the PDF materials or feel free to contact us.

Profect Co., Ltd. will hold a seminar on October 3rd (Friday) themed around the IT Implementation Subsidy 2025 and our developed and sold production management system "TED." This year's IT Implementation Subsidy has seen a significant decrease in the acceptance rate compared to previous years. Many companies are struggling with the situation of having wanted to implement IT tools but being rejected. In this seminar, we will explain why the acceptance rate has dropped, the background behind it, and the key points for being accepted. Additionally, we will introduce our initiatives that have achieved a 100% acceptance rate so far this year and the reasons why our production management system "TED," registered as an IT tool, is chosen. To accommodate busy schedules, this seminar will be held in a hybrid format, allowing for both in-person attendance and online participation via Zoom. Please choose your preferred method of participation according to your convenience. If you are currently considering applying for the IT Implementation Subsidy or are interested in production management, we encourage you to join us. We sincerely look forward to your application.

An international forum aimed at promoting the circular economy and closed-loop economy, "Closed Loop Recycle Forum 2025 (hereinafter referred to as CLRF2025)," will be held for two days from November 25 (Tuesday) to 26 (Wednesday) at The Oriental Terrace in Chuo Ward, Hamamatsu City, Shizuoka Prefecture. In Europe, closed-loop recycling practices are already advancing. We have organized this international forum as a platform to connect the forefront of Europe with Japan's challenges, striving for a future that balances economic viability and environmental sustainability. A total of 12 speakers, including Chairman Kajiwara of the Waste and 3R Research Foundation and Director Kaneko of the Ministry of the Environment's Container and Packaging Recycling Division, along with leading recycling operators and researchers from Japan and Europe, will present advanced examples of the circular economy and closed-loop economy. Furthermore, through discussions on the feasibility and challenges of implementation in Japan, we will explore hints for sustainable business models that companies and local governments should aim for.
