Weir Type Rubber Lined Diaphragm Valves are engineered to meet international standards, offering exceptional durability and performance. The unique design ensures that the flowing media does not contact the valve's working components, significantly extending the valve's service life. These valves feature a self-draining function, effectively preventing residue buildup and maintaining a cleaner and healthier pipeline system. Available in a variety of body materials, including cast iron, ductile iron, and cast steel, the valve can be lined with specialized materials such as Glass, ETFE, PFA, PVDF, or Halar rubber, which can be customized to meet specific application requirements.
