Construction
- Diaphragm valves don’t have gland seal. External sealing is ensured by thin metal discs (diaphragms) ensuring hermetic sealing of the area through which the fluid flows.
- The materials used for the main parts are: • ST-UNI EN 12165 – CW 617N hot-forged brass for the body and the cap; • nylon for the seat sealing gasket; • harmonic steel for the spring.
