Thank you for visiting the 26th Interphex Japan Exhibition from June 26 (Wednesday) to June 28 (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.

Achieving high maintenance efficiency with a unit-based design! A diaphragm valve with high airtightness, zero seat leakage, and excellent corrosion and chemical resistance.

This catalog features a variety of diaphragm valves manufactured and sold by Nihon Diaphragm Valve Co., Ltd. A diaphragm valve is a type of valve that uses a flexible diaphragm made of materials such as rubber to open and close the flow path. They are broadly classified into two types: the wear-resistant type with high airtightness and the straight type with low pressure loss and minimal liquid accumulation. The catalog includes a diverse range of products, including manual operation valves, air-operated ON-OFF valves, and electric operation valves.

On September 15, 2026, we issued a press release regarding the wooden lightweight sheet "Hyper CLT Sheet." The Hyper CLT Sheet is a civil engineering sheet that utilizes CLT (Cross-Laminated Timber) stacked in an orthogonal direction. It can be used in various locations such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 version weighs approximately 230 kg, making it relatively lightweight and easy to install, remove, and relocate. Additionally, it offers environmental benefits such as reducing glare and metallic sounds typical of wood, as well as CO2 fixation. Furthermore, it can be proposed for the use of new technologies in public works as a **registered technology with the Ministry of Land, Infrastructure, Transport and Tourism "TH-250021-A."** Through this press release, we aim to expand the new wooden lightweight sheet that combines wood, NETIS, civil engineering, and CLT to more construction sites.

● The production time for cast prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly producing sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or varying dimensions, can be molded at the same time in one molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Repairs using conventional welding methods often change the base material around the crack due to heat, leading to residual stress and deformation, which constantly carries the risk of "crack recurrence" and "secondary damage." Hinode Waterworks Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be carried out 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.
