Alfa Laval Unique Ultra Clean
Applying the Alfa Laval Unique Ultra Clean
Alfa Laval has a wide range of sanitary valves fitted with a double seat. The Alfa Laval double seat valve is characterized by a dual seal which minimizes the risk of undesired mixing of two different liquids. Should a seal fail, then the leaking fluid is discharged via the so-called leak detection and this can be observed visually. The Alfa Laval double seat valve program is divided into leak valves and double seat valves leak.
Alfa Laval's leak detection valves (SMP-type BC and SMP-BCA) are provided with a pair of seals mounted on a single spindle. The service leakage cavity via a separate connection to be cleaned. In the open position, both the supply line of the cleaning liquid when the discharge from the leak detection closed automatically by means of built-in shut-off valves. All mixproof leak detection valves of Alfa Laval has two seals which can move independently. In addition, these valves switch leak and the leakage cavity remains at all times (even during CIP) atmospheric.
Alfa Laval Unique
The Alfa Laval double seat valve Unique mixproof leak detection is characterized by a modular structure. Depending on the application both the lower and upper spindle can be equipped with an independent seat lift, balancing and/or external rinsing. Also the external flushing of the leakage cavity as possible.
The mixproof leak detection valve type SMP-SC is equipped with both a lower and upper seat lift as well as a balancing of the lower spindle. Optionally an external coil connected to the balancing available. Alfa Laval also has a double seat leak detection tank bottom valve (Type SMP-TO) in its package, as well as aseptic double seat valve leak detection type AMP. For replacement of the seals on the spindle auxiliary tool is needed. Its use is relatively simple and is clearly illustrated in the detailed instruction manual or on the CD-ROM instruction. All double seat valves are manufactured from 316L stainless steel and fitted with EPDM sealing. Optionally, NBR, HNBR (Unique) or FPM available.
