Achieving high maintenance performance with a unit-based design! A diaphragm valve with zero seat leakage due to high airtightness, excellent corrosion and chemical resistance.

This catalog features a variety of diaphragm valves manufactured and sold by Japan Diaphragm Valve Co., Ltd. A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm made of materials such as rubber. They can be broadly classified into two types: the wear-resistant type with high airtightness and the straight type with low pressure loss and minimal liquid accumulation. The catalog includes a diverse range of products, including manual operation valves, air-operated ON-OFF valves, and electric operation valves. Additionally, technical materials such as dimension and material selection tables are included at the end. [Contents] ■ Manual operation valves ■ Air-operated ON-OFF valves ■ Air-operated flow control valves ■ Electric operation valves ■ Technical materials, etc. *For more details, please refer to the PDF materials or feel free to contact us.

Introduction of porcelain lining products with excellent resistance to corrosion and chemicals.

The "480(04) type" is a diaphragm valve made of porcelain lining that excels in corrosion and chemical resistance. It does not experience the permeation of chemical liquids, which can be a concern under certain conditions with fluororesin lining or rubber lining. Additionally, it is suitable not only as a corrosion-resistant valve for strong acidic fluids but also for highly permeable fluids such as hydrochloric acid and phosphorus trichloride. 【Features】 ■ Does not experience the permeation of chemical liquids, which can be a concern under certain conditions with fluororesin lining or rubber lining. ■ Suitable not only as a corrosion-resistant valve for strong acidic fluids but also for highly permeable fluids such as hydrochloric acid and phosphorus trichloride. ■ Base material: FCD-S, Lining: Porcelain *For more details, please refer to the PDF materials or feel free to contact us.

Many delivery achievements for pharmaceutical and food plants, as well as high-purity chemical solutions! It can completely block corrosive fluids.

At Nippon Diavalve, we handle "corrosion-resistant valves with clamp connections" made of a body lined with fluororesin (ETFE). 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.

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.
