Abstract

Si tratta di un anello di tenuta (6) in particolare da usare nelle valvole. Esso presenta un corpo (19), con il quale esso viene trattenuto in un incavo (7). Sulla periferia opposta (14) al fondo (17) dell'incavo (7) è sistemato uno strato di scorrimento (18) sul corpo (19) in materiale più duro rispetto al corpo di tenuta.
