Weir Type Diaphragm Valves are built to international standards. These valves are designed so that the flowing media does not touch the internal components, which greatly increases their service life. They also feature a self-draining function, which helps ensure no residue is left behind, keeping the pipeline clean and hygienic.

The valve body comes in different materials, such as cast iron, ductile iron, and cast steel. The valve can lined with materials like Glass, ETFE, PFA, PVDF, and Halar rubber, and can be specially processed to meet specific needs. These valves are ideal for various industrial applications, offering both durability and reliability.
