Thank you for visiting the 34th Plant Show INCHEM TOKYO 2021 from November 17 (Wednesday) to November 19 (Friday) 【Nihon Diavalve】.

Easy with 90-degree operation! Prevents over-tightening and damage! We solve concerns like "I'm worried if it's securely tightened..."

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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without affecting the base material with heat. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
