Inspection
Before assembling the solenoid valve make sure that a
thorough inspection of all the components is carried out.
Remember that although a failed component may be easy
to identify, the cause may be less easy to trace. It is also
possible that a failed component may have caused
damage to other areas of the valve.
1 Carefully clean all components using a suitable
degreasing agent.
2 Carefully inspect all components for signs of
excessive wear or damage. If wear or damage is
evident, components must be renewed.
