Diaphragm Control Valve, Cast Iron, 1/2-8 IN, Class 150 LB

Key Specifications / Features

The Diaphragm Control Valve operates like a pinch clamp, sealing with a flexible diaphragm against a transverse weir. It's optimal for handling sticky fluids, slurries, corrosive, and hazardous substances, ensuring leak-tight closure. Ideal for high-purity fluids, it prevents contamination. With its low-pressure design due to a large diaphragm area, it's widely used for On/Off and throttling services in industries like Waste & Water Treatment, Filtration, and Chlorination. This valve is crucial for maintaining purity in fluid handling applications, making it indispensable for systems requiring precise control and resistance to contamination.
