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.

A structure that opens and closes the flow path with a flexible diaphragm! We will introduce two types of valve designs.

The product consists of three units: the drive part, diaphragm, and main body. It controls the fluid by pressing the diaphragm against the sealing part of the inner surface of the main body and then releasing it. The wear-type "Model 400" maintains airtightness by ensuring that the diaphragm and the main body's dam are in close contact without gaps, demonstrating high valve seat sealing performance. The materials for the main body and diaphragm are diverse, allowing compatibility with a wide range of fluids. Additionally, the straight-type "Model 500" features a flow path that is nearly linear, resulting in a structure with minimal pressure loss and liquid pooling, making it suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. 【Features】 ■ No leakage to the outside and no contamination of the fluid from outside air ■ Zero valve seat leakage ■ Simple main body shape suitable for lining processing ■ Minimizes liquid pooling and possesses self-cleaning properties ■ Adopts a three-unit system, making disassembly and assembly easy *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
