Note

Hint!

TEFASEP gold valve seat seals achieve optimal sealing only after an initial CIP or SIP
cleaning.
CIP or SIP cleaning operating conditions:
-Medium: lye, hot water or saturated steam
- Temperature: >80 °C (176 °F)
- Hold time: 20 … 30 min
The valve must be brought to the closed position for a brief period (3 minutes)
immediately after CIP or SIP cleaning.
During commissioning, regularly check all sealing points for leaks.
Exchange defective seals and repeat the CIP or SIP process.
