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

This catalog features a variety of diaphragm valves manufactured and sold by Japan Diaphragm Valve Co., Ltd. A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm made of materials such as rubber. They can be 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.

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 a flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear Type Diaphragm Valve: 400 Series" 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 compatibility with a broad range of fluids. ▼Applicable Fields: Chemicals, Environmental & Water Treatment, Steel, Shipbuilding, Pharmaceuticals, Food, Semiconductors, Power Generation, etc. *For more details, please refer to the catalog (P6-P14) or feel free to contact us.

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

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 valve's open and closed status can be clearly seen from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. Please try the easy operation and stable closing performance of the 90-degree rotating lever handle. 【We solve the following 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 lifespan. *For more details, please refer to the PDF materials or feel free to contact us.

In anticipation of the quantum era, where traditional cryptographic techniques will become ineffective, there is an urgent need to transition to post-quantum cryptography (PQC). However, cryptographic technologies, including public key cryptography, which are considered vulnerable to the influence of quantum computers, are used in various aspects of society. Understanding the locations and situations of their use is already quite challenging, and the transition involves a wide range of stakeholders, making the shift to PQC not straightforward. This seminar will explain the latest trends in post-quantum cryptography and the initial steps for a smooth transition, covering aspects that businesses should consider, such as current status assessment, planning, organizational structure, stakeholder coordination, and allocation of management resources, as well as related solutions. <Session 1> Latest Trends in Post-Quantum Cryptography and Initial Steps for Transition Speaker: Ayaka Fukazawa, NRI Secure Technologies <Session 2> Three Specific Strategies for Transitioning to PQC and International Examples Speaker: Hiroshi Ikeda, Thales DIS Japan [Target Audience] - Those considering a transition to post-quantum cryptography (PQC) - Personnel from security and information systems departments
