Application
To minimise risk of implosion of tanks exposed to vacuum
(e.g. during emptying, cool rinsing after hot-cleaning
(max. 85 °C) or caustic cleaning in a CO2 atmosphere). To be
applied on any closed tank.
Construction
The dead weight anti vacuum valve is available in two
versions:
• Integrated in to a SCANDI BREW® tank top system
• Mounted on its own counter flange
The advantages of an integrated anti vacuum valve are lower
initial costs, superior hygiene and smaller area required to
seat valve.
The valve is available in the following sizes:
The size and setting of the anti vacuum valve is based on the
tank design data, cleaning procedure and process requirements.
The anti vacuum valve is produced in a sanitary and robust
design.
Materials
All metallic parts: Stainless steel AISI 304
(or acc. to customer specification)
O-ring seal: NBR, 45° shore
All other parts: Non-toxic food grade materials
It is very important to note that if the cleaning procedure
includes hot-cleaning (max. 85 °C) the valve should be
dimensioned with the purpose of preventing implosion from
the vacuum that appears when flushing with cold water.
