Notice of participation in the "25th INTERPHEX Japan" from July 5 (Wednesday) to July 7 (Friday).

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.

No short pipe section and a small dead leg! A compact design sample collection valve.

The "Bio-Clean Diaphragm Valve" is a dedicated valve for sample collection. Since it does not use a cheese fitting, there is no short pipe section, resulting in a smaller dead leg. Additionally, its compact design and lightweight construction reduce the load on the piping. It can be widely used for introducing and discharging branch flows, merging (mixing liquids), cleaning water, and sterilizing steam. 【Features】 ■ Does not use a cheese fitting ■ No short pipe section, resulting in a smaller dead leg ■ Compact installation due to the integrated structure of the main pipe and body ■ Mass reduced by an average of 23% compared to conventional products ■ Reduced load on piping due to lightweight design *For more details, please refer to the materials. Feel free to contact us with any inquiries.

No adhesion of tablets or powder particles, excellent cleaning properties!!

We handle "valves exclusively for the discharge of tablets and powder granules." With a shape and structure that minimizes tablet residue, we offer a "damper" for safe tablet discharge, and a "butterfly valve" designed for lightweight construction, making installation and removal easy. The main components are made of stainless steel and have a buff-polished finish, ensuring no adhesion of tablets or powder granules and excellent cleanability. 【Features】 <Damper> - Structure that does not crush tablets when opening the damper - Equipped with a stopper at the opening and closing position to reliably maintain the position <Butterfly Valve> - Lightweight design for easy installation and removal on containers and piping - Quick assembly and disassembly due to the clamp method, making cleaning easy *For more details, please refer to the PDF materials or feel free to contact us.

An evolved version of the bio-clean diaphragm valve. The structure eliminates liquid pooling by positioning the valve shaft horizontally. A solution for dead space!

The self-draining type is a valve body that further enhances the liquid retention prevention effect of the Bio-Clean diaphragm valve series. When this valve is installed on horizontal piping, it is designed to eliminate liquid retention by positioning the valve shaft horizontally. 【Specifications (excerpt)】 ■ Stainless steel body (Applicable nominal diameter (DN): 8 to 100) ■ Lined body (Applicable nominal diameter (DN): 15 to 50) ■ The surface finish classification of the body and diaphragm specifications conform to standard specifications. ■ Various drive components for manual operation valves and air-operated ON-OFF valves can be used interchangeably. *For more details, please refer to the PDF materials or feel free to contact us.

Tanks from approximately 10L to 10,000L are acceptable! The opening and closing is done solely by the diaphragm, allowing for smooth discharge of the tank contents with almost no residue left.

【Features】 ● The structure is directly welded to the bottom of the tank, providing excellent stirring efficiency. ● There are no contact parts such as gland packing, stem, seat, or gasket; the opening and closing are done solely by the diaphragm, allowing for smooth discharge of the tank contents with minimal residue. Contamination caused by valve components is extremely low, and cleaning and sterilization can be easily and reliably performed. ● The applicable nominal diameters range from DN15 to 100 (4S), making it suitable for use with small containers of about 10 liters to medium tanks of about 10,000 liters. 【Specifications (Excerpt)】 ● Main body material: SUS316L ● Applicable nominal diameter (DN): 15 to 100 ● Operation method: Manual operation and air-operated methods are both applicable. * For more details, please refer to the PDF materials or feel free to contact us.

Diverging, merging, and the introduction and discharge of cleaning water and sterilizing steam are "applicable." The internal shape of the valve has no dead space, making it ideal for preventing liquid accumulation.

**Features** - It can be directly mounted inside the piping, is compact, and has a structure that prevents fluid residue inside the valve. - It can be widely used for applications such as branching, merging (mixing liquids), introducing and discharging cleaning water or sterilizing steam. **Specifications (Excerpt)** - Main body material: SUS316L - Applicable nominal diameter (DN): Standard combination of main pipe and valve: 15 to 50 (other ranges available as options) - Operation method: Manual operation and pneumatic operation methods are both applicable. *For more details, please refer to the catalog (P.20) or feel free to contact us. (An English version is available upon request!)*

"The New AI Tools Are No Longer Needed" This seminar allows participants to experience Microsoft Copilot, which can be used directly within familiar Word, Excel, and Teams, through a demonstration of actual operating screens. The answers are already within your existing Microsoft 365. You can use AI directly in Word, Excel, and Teams without the need for additional tool selection, all within the security framework of M365. We will explain the basics to practical applications of Copilot in 90 minutes, aimed at executives and managers in the manufacturing industry. We sincerely look forward to your participation. 【Recommended for】 - Executives and managers in the manufacturing industry who have not yet mastered generative AI/Copilot - Those considering AI implementation but are stalled due to tool selection, security, or promotion systems - Those who prefer to see "actual screens" rather than just "reading" before making a decision - Those who are concerned about security and cannot use ChatGPT in their company

We will be exhibiting at "CEATEC 2026," which will be held at Makuhari Messe from October 13 to 16. We provide information technology and process informatics (PI) that optimize "how to create" using physical simulations, AI, and machine learning in process development.

In recent years, weather risks that affect construction sites, such as localized heavy rain, strong winds, and extreme heat, have been increasing. In response to this situation, more companies are implementing weather information services at the company or branch level to manage weather risks across multiple sites collectively. On the other hand, is there a challenge where "the company checks weather information, but it is not used much on-site"? To implement weather measures across the entire company, it is important not only for managers to easily grasp multiple sites but also for the personnel working on-site to be able to easily check the information necessary for their specific site. We are releasing a new feature called "Field View." For more details, please visit our website.
