Key Specifications / Features
The ASTM A216 WCB Diaphragm Valve, designed as a Weir type and manufactured in compliance with BS 5156 and MSS SP-88 standards, features a carbon steel body with a fluorine lining for enhanced corrosion resistance. With a 6-inch (DN150) size, Class 150 LB (PN20) pressure rating, and RF ends for secure connections, this valve is ideal for handling aggressive fluids in industries such as chemical processing, pharmaceuticals, and food processing.
Weir Type Rubber Lined Diaphragm Valves are manufactured according to international standards. The unique design ensures that the flowing media does not come into contact with the working components, significantly extending the service life of the valve. These valves feature a self-draining function to prevent residue build-up, ensuring cleaner and healthier pipelines. The valve body is available in various materials, including cast iron, ductile iron, and cast steel. Lining materials such as Glass, ETFE, PFA, PVDF, and Halar rubber can be specially processed to meet specific requirements.
