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.

~ A high-efficiency customer attraction strategy where homebuyers come in saying "I saw it on ○○!" and a product/design strategy that is specifically requested as "I want to build with Harbor!" ~ In an era where simply creating a "good house" is not enough to survive, rising material costs, labor shortages, and intensifying competition with major companies have made the environment surrounding local construction companies more challenging than ever. Amidst this, Harbor House, which has been established for 19 years in the fiercely competitive Niigata Prefecture, has achieved an annual completion of 450 houses and is now the number one in the number of starts in Niigata Prefecture. Its strength lies not in a single charismatic leader, but in a thoroughly refined "system." Customers who say, "I came after seeing your website" are reliably guided to contracts through a high-efficiency sales flow based on "batting average management." In this online seminar, we will generously share the know-how of customer attraction, product, and management that Harbor House practices with business owners. We will present the shortest route to becoming a "construction company that continues to be chosen" in your business area. ◇ Detailed information and application https://x.gd/pUe2b ◇ Phone inquiries TEL: 025-383-8881
