Fluorine Lined Diaphragm Valve, BS 5156, WCB, DN50, PN10

Key Specifications / Features

The Fluorine Lined Diaphragm Valve is designed per BS 5156 and MSS SP-88 standards, featuring a carbon steel ASTM A216 WCB body with a fluorine lining for superior chemical resistance. Sized at DN50 (2 inches) with a PN10 (Class 150 LB) pressure rating, it is equipped with raised face (RF) flanged ends for secure installation.

Weir Type Rubber Lined Diaphragm Valves are engineered to meet international standards. These valves offer significantly extended service life because the flowing media does not come into contact with the working components. Featuring a self-draining function, the valves ensure no residue remains, keeping the pipeline cleaner and more hygienic. The valve body is available in a variety of materials, including cast iron, ductile iron, and cast steel. The lining materials—such as Glass, ETFE, PFA, PVDF, and Halar rubber—can be customized to meet specific requirements.
