DIAPHRAGM VALVE (UNI/DIN/BS)

Diaphragm Valve (UNI/DIN/BS)
The Diaphragm Valve is used to shut off or regulate flow in piping systems. It operates by pressing a rubber or PTFE diaphragm against the valve seat to block the flow. With a simple design, high corrosion resistance, and excellent sealing performance, diaphragm valves are widely applied in chemical, food, pharmaceutical, and water treatment industries. The valve is manufactured according to European connection standards (UNI – Italy, DIN – Germany, BS – United Kingdom).
