EPDM Lined Diaphragm Valves, BS 5156, Ductile Iron, DN50, RF

Key Specifications / Features

The EPDM Lined Diaphragm Valve, manufactured to Weir Type design and compliant with BS 5156 and MSS SP-88 standards, features a durable ductile iron body for long-lasting performance. Sized at DN50 (2 inches) and rated for PN16/Class 150 LB pressure, it is equipped with RF flanged ends for secure installation. The EPDM lining ensures excellent chemical resistance, making this valve ideal for handling aggressive fluids in industrial applications.

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.
