It was published in the September special issue of the monthly magazine "Piping Technology"!

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. (We have English and Chinese versions of the catalog available upon request!)

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.

We have introduced our commercial aroma diffuser "Majesta Fragrance" at a karaoke bar located in the city. The model we installed is [MF-02S]. From the moment customers open the door, a gentle fragrance spreads throughout the store, enhancing the atmosphere. We hope to create a memorable store that customers will want to visit again through the use of fragrance. Majesta Fragrance is available for a free trial installation exclusively in the Kanto area. If you are interested in our fragrance services, please feel free to contact us.

We have introduced our Majesta Fragrance in the restrooms of a company located in the city. The model we implemented is the compact-sized MFmini. By adding fragrance to the clean space, we have created an environment where users can spend their time more comfortably. The restroom, which is used daily, has become a more pleasant and high-quality space.

Thank you very much for always using Majesta Fragrance. Our company will be open as usual during the Obon period. Please feel free to contact us for inquiries about scent arrangements or the introduction of commercial aroma diffusers.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
