the identification of the valve easier and contains:

3. Requirements for maintenance staff
The staff assigned to assembly, operating and maintenance tasks should be qualified to carry out
such jobs and in any circumstance, ensure personal safety
4. Transport and storage
Transport and storage should always be carried out with the ball complete closed and the valves
should be protected against external forces, influence and destruction of the painting layer as well.
The purpose of the painting layer is to protect the valve against rust, during transport and storage.
The valves should be stored in an unpolluted space and should also be protected against all
atmospheric circumstances. There should be taken care of the temperature and humidity in the
room, in order to prevent condensate formation.
5. Function
ECON ball valves are designed to stop the flow of a medium. The valve is closed by turning the
lever clockwise; please don't use tools to increase the torque on the lever. It is recommended to
use the ball valve in a complete open or closed position. An intermediate position must be avoided
as much as possible, to protect the seats.
6. Application
The ECON ball valves are used in industrial applications with clean gasses and liquids. The valves
are designed for standard operating conditions. For the use in extreme conditions e.g. highly
corrosive media, it is recommended to mention this at the ordering stage, to verify whether the
valve is suitable. The installation designer is responsible for the valve selection, suitable for the
working conditions. The valves are unsuitable, without written permission of an ERIKS company,
to apply for hazardous media as referred into Regulation (EC) No 1272/2008.
