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.
