DIAPHARGAM VALVE

Valves

Coating: RAW / BLUE PAINT

Available Size: 1/2" - 12"

🔎 What It Is:

A Diaphragm Valve is a type of valve that controls fluid flow using a flexible diaphragm. The diaphragm presses against a seat or weir to close the valve, and lifts to open it. These valves are ideal for applications requiring clean operation, corrosion resistance, or precise throttling. Common in industries like pharmaceuticals, water treatment, and food processing.
