1. General
The instructions and list of spare parts are applicable to
ShearStream SB ball sector valves in accordance with
catalogue sheet FCD NFEETB4152-01.
2. Lifting
All lifting must be carried out on the valve itself and not
on the actuator. The joint between the valve and the actua-
tor is designed for carrying the operating torque and the
weight of the actuator - see Fig. 1.

3. Receiving Inspection
All valves leaving our plant are inspected and tested in
accordance with the relevant requirements or in accor-
dance with the requirements specifi ed by the purchaser.
Valves equipped with actuators are subject to functional
testing and are adjusted in such a manner that every unit
is completely ready for direct installation in the pipework.
However, in view of damage that may have occurred
during transport, it is advisable that receiving inspection
is performed.
We would suggest the following inspection procedure:
- Check that the valve delivered is correct in
terms of type, size, equipment, etc.
- Examine the valve, actuator and valve positioner
regarding possible damages.
