Notice of Revision for the "Diaphragm Valve Catalog" (Also introducing case studies and FAQs!!)

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.

High Strength, Low Cost: The Economic Advantages of Carbon Steel Frames Carbon steel is inherently strong, and this high structural strength ensures stable wind resistance while allowing for a simple support structure, reducing the need for extra components. This also lowers the wear rate during transportation, enabling further savings in material costs and installation expenses. Transportation and Construction: Streamlining the Entire Project The advantages of carbon steel frames are also evident in the transportation and construction phases. Standardized designs simplify on-site installation and shorten construction periods. For example, carbon steel frames can be packaged using a combination of wooden sticks and iron ties, improving unloading efficiency and increasing transport volume. This reduces construction time and labor costs, distributing the overall burden of the project across all stages. Technological Innovation: Breakthroughs in Corrosion Resistance With the evolution of material technology, the corrosion treatment of carbon steel frames has also significantly advanced. Grace Solar has adapted to the technological trends in process development, and all current carbon steel frames utilize AlMgZn coating. At the same time, to meet the special requirements of each project, our company offers custom options for hot-dip galvanizing.
