Thank you for visiting the 24th Interphex Week Tokyo from July 13 (Wednesday) to July 15 (Friday) - Japan Diavalve

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.

These valves are suitable for addressing corrosive fluids in sanitary piping, preventing crevice corrosion caused by chloride ions, and mitigating the leaching of metal ions. With the diaphragm valve's characteristics of "air-tightness" and "corrosion resistance," they can completely shut off corrosive fluids. We have a wealth of experience in pharmaceutical and food plants, as well as in high-purity chemical lines. 【Features】 ■ Body Material: SUS316L ■ Lining Material: ETFE ■ Connection Method: Clamp Joint (ISO2852) ■ Applicable Nominal Diameter: 25A to 65A (1S to 2.5S) *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.

Regarding the "quotation" used at the forefront of sales activities: "Do we need to save everything when we revise it to Ver.1, Ver.2, etc., every time the amount or specifications change?" "Should we also keep the data from other companies that were not selected in competitive quotations?" Have you ever wondered about these questions? The Electronic Bookkeeping Act strictly demands the "authenticity" of data, but saving all processes is a significant burden for the field. This time, we will clearly explain the boundaries of the preservation obligation in a case study format, incorporating interpretations from the latest National Tax Agency Q&A. *You can read the full text from the note in the "Related Links." [Contents of this article] 1. The boundary of the preservation obligation lies in "sending to external parties." Items sent externally are "generally required to be preserved." Items that have not been sent externally have "no preservation obligation." 2. Judgment from the sending side: "Is it linked to a transaction?" 3. Judgment from the receiving side: "The perspective of the 'Corporate Tax Act' is important." ■ Note! "Version revisions" and "corrections/deletions" are different things. ■ A smart way to ensure reliable "version management." ■ Summary.

The first store of the new business format, Petrichor Bakery and Café, developed by Sanmarc Holdings. The name "Petrichor" means "the smell of earth that rises from the ground after it rains." It was named with the desire to provide a place where people can take a break and refresh themselves in a healing space away from the hustle and bustle of everyday life. We have adopted it for the main counter's tabletop. The atmosphere of the counter's tabletop has satisfied the client! Color pattern: Shell FS115 Produced by: Sanmarc Holdings Co., Ltd.
