dotata di una sfera rotante con un foro per avviare, arrestare o regolare il flusso ed \u00e8 molto apprezzata per la sua resistenza alla corrosione, la tenuta affidabile e la lunga durata.<\/p>\n<p>Caratteristiche principali<\/p>\n<ul>\n<li>Funzionamento rapido: bastano solo 90\u00b0 di rotazione per aprire o chiudere completamente, con bassa resistenza al flusso ed elevata efficienza.<\/li>\n<li>Eccellente resistenza alla corrosione: realizzato principalmente in acciaio inossidabile 304\/316L, adatto per acqua, olio, gas, prodotti chimici e fluidi leggermente corrosivi.<\/li>\n<li>Prestazioni di tenuta superiori: sigillate con guarnizioni in PTFE, RPTFE o PEEK, garantiscono zero perdite e prestazioni stabili.<\/li>\n<li>Ampio intervallo di pressione e temperatura: adatto a condizioni di lavoro ad alta pressione e alta temperatura.<\/li>\n<li>Connessioni multiple: sono disponibili estremit\u00e0 filettate (NPT\/BSP), flangiate, saldate e a saldare a tasca.<\/li>\n<li>Lunga durata: resistente all&#039;usura, anticalcare, di facile manutenzione, adatto a un utilizzo frequente.<\/li>\n<\/ul>\n<p>Tipi principali<\/p>\n<ul>\n<li>valvola a sfera
