Castel Diaphragm Valves

MODEL # 6220 shown. Multiple Models and Sizes available in stock

Diaphragm valves do not have a gland seal. Thin metal discs (diaphragms), which hermetically isolate the spindle chamber from the fluid flow area, ensure the external sealing. The main parts of the diaphragm valves are made with the following materials: • Hot forged brass EN 12420 – CW 617N for the body. • Brass EN 12164 – CW 614N for spindle • Harmonic steel for spring • Nylon for seat sealing gaskets
