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.
