I principali punti di forza della valvola a farfalla wafer (doppia eccentricit\u00e0 + tenuta morbida)
\nVantaggi in termini di struttura e installazione
\nStruttura a doppio eccentrico: l'albero della valvola \u00e8 a doppio disassamento. Quando la farfalla si apre di circa 20\u00b0, si distacca dalla sede della valvola. Ci\u00f2 riduce significativamente l'attrito, richiede una coppia di serraggio inferiore e garantisce una lunga durata.
\nCollegamento a morsetto: nessuna flangia integrata. Struttura compatta, peso ridotto, ingombro ridotto e installazione rapida.
\nFacile da installare, smontare e riparare: la sede della valvola pu\u00f2 essere sostituita indipendentemente senza smontare la piastra a farfalla o l'albero della valvola, con conseguente riduzione dei costi di manutenzione.
\nCaratteristiche principali in termini di tenuta e prestazioni
\nPerdita zero bidirezionale: guarnizione morbida (EPDM\/NBR\/PTFE) + sede flessibile\/a labbro, guarnizione a bolla
\nTenuta dinamica: maggiore \u00e8 la tenuta, maggiore \u00e8 la pressione. Compensa le variazioni di temperatura e pressione.
\nBassa resistenza al flusso + Eccellente regolazione: Caratteristica di flusso in percentuale pressoch\u00e9 uguale, doppia funzione di interruzione e regolazione
\nNessun inceppamento in apertura e chiusura: basso attrito, bassa coppia, adatto per applicazioni manuali\/a turbina\/pneumatiche\/elettriche
\nMateriale adeguato alle condizioni di lavoro
\nMateriali di alta qualit\u00e0: corpo valvola in WCB\/304\/316; piastra a farfalla in acciaio inox; sede valvola disponibile in diversi materiali elastici a scelta.
\nAmpia applicabilit\u00e0: acqua, olio, gas, vapore, fluidi debolmente corrosivi; da -30\u2103 a 180\u2103 (a seconda dei componenti di tenuta)
\nElevata durata: resiste a decine di migliaia di operazioni di apertura e chiusura senza subire perdite, risultando adatto a frequenti commutazioni.
\nCosto e rapporto qualit\u00e0-prezzo
\nLeggero ed economico: grazie al peso ridotto del 30%+ rispetto alle valvole a farfalla flangiate, il carico sulla tubazione e i costi di installazione si riducono.
\nLunga durata + Manutenzione semplice: riduce i tempi di inattivit\u00e0 e il consumo di pezzi di ricambio, e presenta un costo totale contenuto durante l'intero ciclo di vita.<\/p>\n
