| The Lewis
automatic valve grinding technology is the result of
a joint development with Queensland Alumina Ltd.
Patent applications have been filed on behalf of the
owners of this technology. |
| |
|
|
The on-board grinding controller
automatically advances the valve disc
towards it’s seat at appropriate intervals
to ensure maximum grinding rate is
maintained.
This eliminates substantial time wastage
between each advance. The extent of each
advance is selectable by the operator to
accommodate scale of differing hardness.
On completion of grinding, or if a fault
occurs, the machine will automatically stop
and alert the operator. |
|
| |
| When grinding Lunkenheimer valves the manual
lock-nut is replaced by a specially developed
clutch, only for the duration of grinding. The
locknut is replaced at the conclusion of grinding
and the grinding machine is moved to the next valve. |
| |
| A standard machine is available to fit valve
actuating drives in the height range of 500mm to
1550mm. |
| |
| The technology is adaptable for a range of valve
sizes and valve types. |
