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.

Exhibits outstanding performance for food resistance and chemical resistance applications! Achieves stable sealing through a uniquely developed shaft sealing mechanism!

The "PFA Lined Butterfly Valve" is a highly reliable corrosion-resistant butterfly valve that is fully lined with PFA. All components that come into contact with the fluid are made of PFA, providing excellent corrosion resistance to most chemicals. The gland mechanism, which has self-sealing and wedging effects, offers high shaft sealing performance against thermal cycles and frequent opening and closing. Additionally, the inclusion of V-packing and coil springs enhances the reliability of the shaft sealing performance against external leakage. 【Features】 ■ Excellent corrosion and chemical resistance ■ High shaft sealing performance ■ Durable casing ■ Resistance to permeation and non-stick properties *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.

[Speaker] Miho Ko Shimada, Partner Attorney, Mori Hamada & Matsumoto Law Firm, Foreign Law Joint Enterprise [Key Lecture Content] The movement towards the implementation of CCS, which is positioned as an essential technology for decarbonizing hard-to-abate industries, is gaining momentum in Japan. Among the "advanced CCS projects" selected for business commencement in the early 2030s, some pipeline projects have progressed to the exploratory drilling stage. For shipping transport projects, discussions are underway to create mechanisms for clustering CO2 sources and improving shipping transport efficiency. In this seminar, following the full enforcement of the CCS Business Act on May 22, we will organize the current state of the business environment related to CCS and examine the latest discussions at the Agency for Natural Resources and Energy and the Ministry of the Environment (based on information available at the time of the event) from a legal perspective as we consider the shape of CCS projects leading to Final Investment Decision (FID). [Lecture Items] 1. Current state of the business environment related to CCS 2. Overview of the CCS Business Act 3. Overview of the cost difference support system for CCS projects (pipelines) 4. Structural considerations through the CCS value chain 5. Q&A / Business card exchange
