<\/div>\n

Questa valvola blocca efficacemente il riflusso di fluidi di media entit\u00e0.<\/p>\n

Il collegamento a flangia ne migliora la tenuta e l'affidabilit\u00e0.<\/p>\n

Caratteristiche strutturali<\/b><\/strong><\/h3>\n

Il disco della valvola si muove verticalmente lungo il corpo della valvola.<\/p>\n

La sua guarnizione si adatta perfettamente e saldamente.<\/p>\n

Le superfici di tenuta della valvola sono costituite da materiali in lega.<\/p>\n

Queste superfici resistono all'usura, al calore e alla corrosione.<\/p>\n

Diversi materiali per il corpo valvola si adattano a varie tipologie di condotte.<\/p>\n

Principio di funzionamento<\/b><\/strong><\/h3>\n

La pressione media in avanti solleva il disco della valvola.<\/p>\n

Il movimento apre completamente il passaggio del fluido.<\/p>\n

Il riflusso fa s\u00ec che il disco si abbassi fino alla sede della valvola.<\/p>\n

Il disco chiuso blocca il flusso inverso del mezzo.<\/p>\n

Parametri tecnici<\/b><\/strong><\/h3>\n

La sua pressione nominale \u00e8 compresa tra PN1,6 e PN10,0 MPa.<\/p>\n

Funziona a temperature comprese tra -29\u2103 e 550\u2103.<\/p>\n

Il suo diametro varia da DN15 a DN1200 mm.<\/p>\n

\u00c8 adatto all'acqua, all'olio, al vapore e ad altri fluidi.<\/p>\n

Installazione e manutenzione<\/b><\/strong><\/h3>\n

Allineare la direzione del flusso con la freccia sul corpo valvola.<\/p>\n

\u00c8 adatto al montaggio su tubazioni orizzontali o verticali.<\/p>\n

Verificare la presenza di usura e corrosione sulle superfici di tenuta.<\/p>\n

Pulire regolarmente le impurit\u00e0 interne della valvola.<\/p>\n

Mantenere il disco della valvola in movimento flessibile verso l'alto e verso il basso.<\/p>\n

Campi di applicazione<\/b><\/strong><\/h3>\n

Serve le industrie petrolifera, chimica ed energetica.<\/p>\n

Ci\u00f2 si applica anche ai sistemi di condotte metallurgiche.<\/p>\n

Garantisce il funzionamento sicuro delle apparecchiature industriali.<\/p>\n<\/div>\n
