Valvole per vuoto
Esistono diversi tipi di valvole per vuoto per coprire l’ampia gamma di applicazioni possibili in ambito industriale e di ricerca. L’eccellente tenuta di una valvola per vuoto è essenziale, ed è proprio ciò che queste valvole garantiscono, insieme a una lunga durata, basse esigenze di manutenzione e tempi brevi di apertura e chiusura. Le valvole per vuoto elettropneumatiche o elettromagnetiche sono ideali per i sistemi che richiedono un flusso di processo automatizzato. La facilità d’uso della valvola per vuoto rappresenta inoltre un aspetto cruciale nel processo decisionale.
