10.3 Servicing intervals
To ensure the highest operational reliability of the valves, all wearing parts should
be replaced at longer intervals. Keep an adequate supply of wearing parts (stem
diaphragms and seals) in your spare parts stock.
In practice, the actual maintenance intervals can only be determined by the user
since they depend on the operating conditions.
Examples of relevant process parameters are:
• daily period of use,
• switching frequency,
• type and temperature of the product,
•
type and temperature of the cleaning solution,
• ambient conditions.
If there is still no or too little information available for the definition of practically-
orientated maintenance intervals, the reference values listed in the following table
can be considered as a basis. The following information is based on the
experience of GEA Flow Components and applies to installations working in a 2-
shift operation.
Hint!
Prior to any work on the open valve, ensure that it has stopped
operation, see section Section 10.4, Page 45
