Detail Information

Product Name: Pneumatic Diaphragm Valve, EPDM Lined
Design Standard: BS 5156
Body Material: Ductile Iron GGG40
Size: DN50, 2 Inch

The diaphragm valve is specifically designed for handling non-corrosive and mildly to moderately corrosive media. Its valve body may be unlined or lined with a range of rubber materials to suit various fluid types and operating temperatures. These lining options offer excellent corrosion resistance, making the valve adaptable to different process conditions. A key feature is the separation of the valve body and bonnet by an intermediate diaphragm, which protects the valve stem and bonnet components from contact with the process media. Structurally, it is a specialized type of globe valve.
