Rubber Lined Diaphragm Valve, Ductile Iron, DN150, Pneumatic

Key Specifications / Features

The Rubber Lined Diaphragm Valve Supplier offers a high-quality valve designed to meet BS 5156 and MSS SP-88 standards. This valve features a ductile iron body with a rubber lining, ensuring durability and resistance to corrosive and abrasive media. It has a DN150 size (equivalent to 6 inches), a PN10 pressure rating (equivalent to Class 150 LB), and RF flanged ends for secure connections. The valve is equipped with a pneumatic actuator for efficient and reliable operation.

The diaphragm valve is specifically designed to control non-corrosive or generally corrosive media. The valve body surface can be unlined or lined with various types of rubber, offering options for different applications. It is suitable for a range of working temperatures and fluid pipelines. The diverse lining materials provide good corrosion resistance and are compatible with various media. The valve body and cover are separated by an intermediate diaphragm, which prevents the valve cover and stem components above the diaphragm from being eroded by the medium. The diaphragm valve is a special type of globe valve.
