Cast Iron Diaphragm Valve
The Cast Iron Diaphragm Valve is a linear motion valve designed to control the flow of liquids, slurries, and corrosive media. It uses a flexible diaphragm to seal off the flow path, ensuring leak-proof performance and preventing contamination. With its durable cast iron body, this valve is ideal for industrial applications that demand reliability, tight shut-off, and low-maintenance operation. It is commonly used in water treatment, chemical processing, and industrial piping systems.
