Pneumatic Diaphragm Valve with Handwheel, Ductile Iron, DN32

Key Specifications / Features

The Pneumatic Actuated Diaphragm Valve Plant specializes in manufacturing valves with ductile iron bodies, ensuring robustness and durability. These valves are designed with a convenient handwheel for manual operation when needed. Available in a size of DN32 (1-1/4 inch), they are rated for a pressure of PN16 (Class 150 LB). The valves feature RF (Raised Face) flanged ends for secure and reliable connections, making them suitable for various industrial applications.

The Diaphragm Valve is engineered to control the flow of non-corrosive or mildly to strongly corrosive media. It features a lined or unlined body, with lining materials such as natural rubber, butyl, EPDM, or hard rubber, making it suitable for various fluid types and operating temperatures. The internal design isolates the working components , such as the valve stem and bonnet, from the process media using a diaphragm, thereby enhancing corrosion resistance and extending service life. Diaphragm valves serve as a specialized type of globe valve, offering reliable shut-off and throttling functions across a wide range of industrial applications.
