VESTA sterile valves by GEA Tuchenhagen
Wednesday 11. March 2009 - The VESTA sterile valve series has been specially developed for the pharmaceutical, food, cosmetic and biotech markets. The valves heart is the PTFE bellows which acts as a sealing element with a patented sealing system and long service life.
Process reliability and maximum product quality are known requirements of sterile applications. In particular, shut-off valves must be reliable as they perform a key role in hermetically sealing the process interior off against the external atmosphere. Shut-off valves also have to be CIP/SIP cleanable.
Successful and reproducible cleaning is only possible – if a Cleaning in Place’ (CIP) procedure is used – if particular design criteria are met. In addition to the quality (topography) of the surfaces in contact with the product, the geometry, above all, has a decisive influence.
VESTA sterile valves: certified by EHEDG
One of the significant development aims was to provide proof of cleanability. Modern development tools – such as flow simulation – were used to draw conclusions regarding the cleaning efficiency as early as possible in the development stage. The results of the EHEDG cleaning test of the VESTA range of sterile valves proved to be more than satisfactory. The EHEDG certification of the VESTA range of sterile valves means that the final building block of the development – namely proof of cleanability – is now in place.
VESTA sterile valves: complete range available
GEA Tuchenhagen now offers the user a full range of applications for larger volume flow rates in extremely sensitive processes where high sterile requirements must be fulfilled. VESTA sterile valves – based on the innovative concept of single-seat, tank bottom and shut-off valves with PTFE bellows – offer process-technological and economic advantages in extremely sensitive processes, now in sizes from DN 10 to DN 65.
The extended program includes the following sizes:
– New – DN 32, 40, 50, 65 (DIN pipe standard)
– New – ISO 42.4, 48.3, 60.3 (ISO pipe standard)
– New – OD 1½”, 2″, 2½”, 3″ (OD pipe standard)
