Come funziona:


La valvola Unique Mixproof si basa su una serie di componenti di base, tra cui corpo valvola, otturatore della valvola, attuatore e opzioni di pulizia e accessori che supportano un'ampia gamma di applicazioni. Usando questi componenti, è possibile costruire una valvola Unique Mixproof per soddisfare i propri specifici requisiti di processo.

Per agevolare la manutenzione, la valvola Unique Mixproof è dotata di fori di rilevamento delle perdite che consentono di rilevare in anticipo l'usura o il danneggiamento degli o-ring statici. Gli operatori possono ispezionare visivamente la valvola in qualsiasi momento senza doverla smontare.

Principio di funzionamento

La valvola Alfa Laval Unique Mixproof è una valvola normalmente chiusa (NC) controllata da remoto tramite aria compressa.

Per separare i due liquidi, la valvola ha due sigilli per gli otturatori indipendenti. Lo spazio tra i due sigilli forma una camera di drenaggio atmosferica. Nel raro caso di fuoriuscita accidentale del prodotto, il prodotto scorre nella camera di drenaggio e viene scaricato attraverso una delle valvole di drenaggio.

Quando la valvola è aperta, la camera di drenaggio è chiusa. Il prodotto può quindi scorrere da una linea all'altra senza fuoriuscite. La valvola può essere facilmente pulita e protetta dagli effetti del colpo d'ariete in base ai requisiti di processo specifici e alla configurazione della valvola. (Non si verificano fuoriuscite di prodotto durante il funzionamento della valvola).

State-of-the-art horizontal mixproof valve

Based on the well proven and exceptionally versatile principle of the Unique Mixproof valves, this horizontal mixproof tank valve features many of the same components, such as the actuator, yoke and seals, and therefore the same spare parts. This provides the benefits of easy serviceability and low total cost of ownership.

Alfa Laval Unique Mixproof Horizontal Tank Valve, can be fitted with any level of sensing and control. It is as standard supplied with seat lift, which enables handling of two different products at the same time, or safe handling of one product while seat-lift cleaning operations are being conducted in the other portion of the valve – all without any risk of cross-contamination. The double tangential design of the valve body ensures full drainability, especially when the valve is mounted at the bottom of a flat-bottomed tank.
