Release from clogs caused by slurry and solids! Achieve smooth operation and high control with the V-cut ball!

■What is the NDV V-Port Valve? It is a ball valve that incorporates a V-cut ball. The opening side of the hemispherical ball is cut in a V shape, which effectively cuts through fibrous materials and solids. It can accommodate abrasive fluids, high-viscosity fluids, and more. It also exhibits excellent performance in heat resistance, wear resistance, and flow regulation. 【Are you facing any of these issues?】 ☑ Malfunction due to clogging in the pocket area... ☑ Malfunction caused by solids mixed in the liquid... ☑ Severe wear on the seat due to slurry fluids... 【Features】 ● V-Cut Ball: The opening side of the ball is cut in a V shape, making it effective for cutting fibrous materials and solids! ● Pocketless Structure: The valve seat is only on the primary side, reducing troubles caused by clogging of solids in the fluid! ● Excellent Heat and Wear Resistance: Capable of sealing from vacuum to high pressure without being affected by temperature and pressure differences! ● Superior Flow Regulation Function: High rangeability and excellent flow regulation performance! 【Main Applications】 Fibrous fluids, slurries, powders, pellets, high-viscosity fluids, etc. *For more details, please refer to the catalog or feel free to contact us.

Switching operations for various flow paths realized with a single unit! Reducing piping costs and saving space!

The 3-way ball valve with T/L ports and a four-sided seat can be used for switching, splitting, and mixing fluids by rotating the ball with a T or L-shaped flow path by 90 degrees. For example, by introducing this valve into a process that is currently using multiple 2-way ball valves for switching, you can rationalize piping in a cost-effective manner. Please make use of this for improving piping systems where fluid switching is necessary! <Features> - The T port allows for the selection of any combination from four switching positions by a 90-degree rotation. - L ports can also be manufactured. - Robust structure with a four-sided seat. - Selection of the drive unit according to application is possible. *For more details, please refer to the PDF document or feel free to contact us.

Resolve troubles occurring in powders, slurries, and highly viscous fluids! It is possible to choose the installation posture according to the piping design!

The Y-shaped three-way ball valve is suitable for highly abrasive fluids such as powders and slurries, as well as for high-viscosity fluids and for passing pigs and spheres used for pipeline cleaning. This product features a wide angle of 135° in its flow path, compared to the standard 90° angle of typical three-way ball valves. The wide-angle flow path design reduces the likelihood of fluid blockage compared to a 90-degree three-way valve, and helps minimize damage to the body and ball when dealing with highly abrasive fluids. Additionally, there are two types of flanges available: straight and 22.5° angled. By combining these two types of flanges in any of three locations, various patterns can be selected. 【Features】 ■ Wide-angle body shape ■ Flexible mounting orientation ■ Ideal ball design with low pressure loss ■ Excellent sealing performance ■ Stable bearing function *For more details, please download the PDF or feel free to contact us.

The flow path is close to straight, with a structure that has low pressure loss and minimal liquid accumulation! It is suitable for fluids containing sludge, suspended solids, and more!

A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Straight Type Diaphragm Valve: 500 Series" features a flow path that is nearly linear (straight), resulting in a structure with minimal pressure loss and liquid accumulation. It is suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. ▼ Application Fields: Water treatment plants, final treatment facilities, etc. *For more details, please refer to the PDF materials or feel free to contact us.

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

The "BQL400NB model" is a rapid opening and closing type handle diaphragm valve from BioClean. While the standard handle type requires about 5 rotations for operation (in the case of 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 identified from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. We invite you to try the easy operation and stable sealing performance of the 90-degree rotating lever handle. 【We solve these 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 the lifespan. *For more details, please refer to the PDF materials or feel free to contact us.

Hello everyone! We are Nikken Coating Industry Co., Ltd., a specialized manufacturer of contract processing for fluororesin coatings and PEEK coatings. Thank you very much for visiting our booth at the recent "Mechanical Elements Technology Exhibition." Thanks to you, we were able to conclude the event successfully. At the exhibition, we proposed surface treatment solutions for the "five challenges (release, sliding, corrosion resistance, impurity measures, and environmental response)" that arise in manufacturing sites. Were there any technologies that caught your interest? ■ We are currently responding to inquiries made at the venue We are sequentially contacting those who made technical inquiries or requests for prototypes at our booth on the day of the event. If you have requests such as "I would like you to look at additional drawings" or "I need a quote urgently," please feel free to let us know. ■ For those who could not attend the exhibition or missed our booth We also welcome inquiries from customers who could not come to the venue, such as "coating for special shapes that other companies have declined" or "switching from existing coatings." If you have any concerns regarding "surfaces," please feel free to consult or contact us.

The particle visualization technology developed under our brand "ViEST" has a very high level of detection sensitivity that allows for real-time visualization of the suspended and adhered states of micro and nano-sized particles. We are engaged in the sale of visualization systems and contract services for evaluation (investigating particles and airflow in production processes, manufacturing equipment, and factory environments, evaluating the performance of cleaning products, proposing yield improvement measures, etc.) both domestically and internationally. In manufacturing environments, invisible fine foreign substances, dust generation, particle adhesion due to static electricity, and airflow disturbances can lead to quality defects and reduced yield. Our company clarifies these contamination factors through visualization technology and provides consistent support from identifying the source of the problem to considering and confirming improvement measures. Do you have any of the following concerns? - Unable to identify the cause of foreign matter contamination - Want to check airflow and cleanliness in clean rooms - Want to understand dust generation from manufacturing equipment and transport systems - Want to reduce particle adhesion to films and substrates - Want to improve contamination that causes yield reduction

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" or "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for metal crack repair without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material with heat. Repairs can be made even 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 or download the catalog.
