Product Description

Product Description

(1)Features
The EgleBergman BestFlow is a
temperature-controlled "money-saving
valve" for double seals on which the
barrier water connection extends directly
into the seal chamber, e.g. DN.

(2)Advantages
• Reduced, minimum barrier water consumption depending on the seal temperature
• Easy installation and use: no additional connection lines needed
• Venting in horizontal and vertical mounting position
• Long-term assurance of the functionality of the expansion element thanks to its physical and chemical properties
• Rugged, fatigue-free moving parts
• No temperature peaks during opening and closing of the valve thanks to the thermosensitive expansion element
• No power supply required (Ex-protection)
• Pressure-balanced component; pressure fluctuations have no effect on the BestFlow; controlled solely via temperature

(3)Functional description
EgleBergman BestFlow controls the
buffer water flow via a thermosensitive
expansion element. If the temperature in
the seal increases above the permitted
value, the valve will open automatically.
More fresh, cool buffer water can then
flow into the seal chamber. As soon as
the seal or the barrier fluid has cooled
down, the valve closes and the flow is
stopped. This ensures that an exchange
of barrier medium only takes place when
cooling of the seal is required. This results
in enormous savings in terms of water
consumption, without any compromise in
terms of operational reliability and safety.
Temperature control for double seals,
which are operated in the non-flow mode.

(4)Recommended applications
• Pulp and paper industry
• Water and waste water technology
• Chemical industry

(5)Notes
Temperature control for double seals,
which are operated in the non-flow mode.
