日本ダイヤバルブ本社　業務・開発部

We have revised the "Diaphragm Valve" catalog and have started distributing "No. D303-08." For those who may not be familiar with diaphragm valves, we have made an effort to edit the catalog to present the necessary product information in a clearer, more accessible, and more visually appealing layout. We hope this will be helpful in selecting diaphragm valves for your daily operations. We would be grateful if you could gain a deeper understanding of our products. Additionally, we offer an electronic version of the catalog on our website. It can be viewed on various devices, including PCs, iPads, iPhones, and Android devices, so please feel free to check it out on your tablet as well. *If you would like to receive a physical copy of the catalog, you can apply through the inquiry page. If you have any questions or concerns, please do not hesitate to contact us. We also have case studies and a FAQ section available. Please check them out in the related catalogs below.
