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.

Exhibits high airtightness and valve seat sealing performance! Excellent in corrosion resistance, chemical resistance, and cleanability.

A diaphragm valve is a type of valve that has a structure for opening and closing the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear-type diaphragm valve: Type 400" is the basic form of a diaphragm valve that has a weir in the flow path. The fluid passage section is streamlined and has no pocket areas, which minimizes liquid accumulation and provides self-cleaning properties. Due to the valve's structure, it exhibits high airtightness and seat sealing performance. There is a wide variety of materials available for the body and diaphragm, allowing it to accommodate a broad range of fluids. ▼Applicable fields: Chemicals, environmental and water treatment, steel, shipping, pharmaceuticals, food, semiconductors, power generation, etc. *For more details, please refer to the catalog (P6–P14) or feel free to contact us.

• valve

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. Additionally, technical materials such as dimension and material selection tables are included at the end.

In a civil engineering site material yard, not only is material storage conducted, but also the frequent movement of trucks and heavy machinery, unloading, and the movement of workers. On unpaved ground, mud and ruts can occur due to rain, which may reduce work efficiency. Hyper CLT mats are civil engineering CLT materials that utilize wood CLT. By laying them in material yards or storage areas, a work space that facilitates the movement of vehicles and heavy machinery can be established while protecting the ground. They can be laid only in necessary locations, and relocation or repurposing in accordance with construction progress is also possible. The 5×10 panel weighs approximately 230 kg, and the 5×20 panel weighs about 460 kg, making them lightweight and easy to install and remove even with small machinery. After use, they can also be utilized as temporary roads, access routes, or heavy machinery work yards. Additionally, they offer unique benefits of wood, such as glare reduction, noise suppression, and CO2 fixation. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," these wooden mats can also be used for environmental improvement in material yards and innovative public works.

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 the application of heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. 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.
