Weir Type Rubber Lined Diaphragm Valves are manufactured to meet international standards. These valves are designed so that the flowing media does not come into contact with the working components, significantly extending the valve’s service life. The Weir Type Diaphragm Valves feature a self-draining function to ensure there is no residue left, keeping the pipeline cleaner and healthier. The valve body is available in various materials, including cast iron, ductile iron, and cast steel. The lining materials include Glass, ETFE, PFA, PVDF, and Halar rubber, which can be specially processed according to specific needs.
