Weir Type Rubber Lined Diaphragm Valves are built to international standards. These valves are designed so that the flowing media does not touch the internal components, which greatly extends their service life. The valves also feature a self-draining function, ensuring no residue remains and keeping the pipeline clean and safe. The valve body is available in materials like cast iron, ductile iron, and cast steel. The lining materials include glass, ETFE, PFA, PVDF, and Halar rubber, which can be customized to meet specific requirements.
