Abstract

Una valvola a farfalla perfezionata per l'intercettazione del flusso di sostanze sfuse o fluide in particolare per i settori farmaceutico chimico e alimentare comprendente un corpo anulare (1) ed una farfalla (3) girevole attorno ad un asse formato da uno stelo (4) ed un perno (4a). Lo stelo (4) è sopportato da un tassello (5) che si impegna amovibilmente nel corpo anulare (1), mentre il perno (4a) si impegna in una sede cieca diametralmente opposta al tassello (5). Una guarnizione (Z) alloggiante nel corpo anulare (1) garantisce la tenuta con la farfalla (3) che è facilmente smontabile per la pulizia della valvola in seguito a estrazione del tassello (5), che può avvenire solo in direzione parallela allo stelo (4) grazie a guide prismatiche realizzate radialmente nel corpo anulare (1). La valvola comprende anche una leva (6) di manovra provvista di una spina di bloccaggio (35) e di una manopola di fermo (30). Il braccio (26) della leva (6) può essere realizzato amovibile dalla bussola (27) in cui è calettato lo stelo (4) ed essere conservato in luogo sicuro per evitare manovre da parte di personale non specificatamente addetto.(Fig. 4).
