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. [Contents] ■ Manual operation valves ■ Air-operated ON-OFF valves ■ Air-operated flow control valves ■ Electric operation valves ■ Technical materials, etc. *For more details, please refer to the PDF materials or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

• valve

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. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

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.
