TECHNICAL INFORMATION

APP. 5

FIELD OF APPLICATION:
Fields of application are stated in the data sheet of each valve series.
If the solids of the medium make up more than 10% the AVK knife gate valve is recommended.
If the medium contains special substances, information of the chemical designation, concentration, and the
temperature of the medium must be given on inquiry of the valves.

OPERATION:
To avoid a seizure of the internal parts, it is recommended to operate the valves with the following minimum
intervals, which at the same time ensures a long durability:
- valves for water and gas: every year
- valves for sewage and industry: every third month

After operation the valve must be:

- fully open and the stem released from stress or
- closed with the closing torque stated in the table
The valve must not be exposed to low temperatures, causing the medium to freeze.
