1 General Information
1.1 Information about this document
These additional operating instructions are part of the user information for the valve.
These additional operating instructions contain the manufacturer's instructions to the operator of
the valve and to all persons who work on or use the valve regarding the procedures to follow.
They include basic instructions for use of the valves. This document is a supplement to the general
standard operating instructions for the ECOVENT angle seat valves and is therefore to be
considered part of it.
These additional operating instructions must be observed before installation and commissioning.

2 Safety
2.1 Intended use
The valve is used for opening and closing pipeline sections.
Proper use of the valve also includes compliance with these operating instructions.
The medium should preferably flow in the opening direction of the valve disk to avoid pipe
hammers when the valve is opened or closed.
In a closed pipe system, hydraulic pressure build-up may occur when the valve switches and result
in seal damage.
Hint!
The manufacturer will not accept any liability for damage resulting from any use of the
valve which is not in accordance with the designated use of the valve. The risk is
borne solely by the operating company.

4.1 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.

4.2 Servicing intervals
To ensure the highest operational reliability, all wearing parts should be replaced at longer
intervals.
The actual servicing intervals can only be determined by the user since they depend on the
operating conditions, for instance:
•daily period of use,
•switching frequency,
•type and temperature of the product,
•type and temperature of the cleaning solution,
•ambient conditions.
