The Weir Type Rubber Lined Diaphragm Valve is manufactured to meet international standards. Since the flowing media does not come into contact with the working components of the valve, its service life is significantly extended. The valve features a self-draining function, ensuring that no residue remains, which helps keep the pipeline cleaner and healthier. The valve body is available in a variety of materials, including cast iron, ductile iron, and cast steel. The lining materials include glass, ETFE, PFA, PVDF, and Halar rubber, and can be specially processed to meet specific requirements.
