Weir Type Diaphragm Valve, Ductile Iron, BS 5156, DN40, PN10

Key Specifications / Features

The Weir Type Diaphragm Valve is a high-quality, durable valve designed for reliable fluid control. Manufactured in accordance with BS 5156 and MSS SP-88 standards, it features a ductile iron body, a rubber diaphragm, and DN40, PN16 specifications. With 1-1/2 inch Class 150 LB and FF flanged ends, this valve ensures secure connections and efficient operation in various industrial applications.

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.
