Notice of participation in the "24th Interphex Week Tokyo" from July 13 (Wednesday) to July 15 (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.

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.

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.

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.
