Nippon Daiya Valve Co., Ltd. List of Products and Services

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 position of the handle makes it clear to see the valve's open and close status even from a distance. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable sealing performance of the 90-degree rotating lever handle. 【We solve the following problems!】 ■ The opening and closing torque is excessive. → It can be reduced, greatly contributing to labor savings. ■ I want to check the open and close status from a distance. → The handle position clearly shows the valve's open and close status even from afar. ■ The valve is damaged due to over-tightening. → 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.

At Nippon Diaphragm Valve, we handle "clamp-connected corrosion-resistant valves" with a body made of fluororesin (ETFE) lining. These valves are suitable for countermeasures against corrosive fluids in sanitary piping, gap corrosion due to chloride ions, and metal ion elution. With the diaphragm valve's features of "air tightness" + "corrosion resistance," they can completely shut off corrosive fluids. We have many achievements not only in pharmaceutical and food plants but also 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.
