Refacing valve cages
Application:
The VD4HD/-30° can be used for refacing the external conical landing face on valve cages.
Capacity:
| Max. refacing diameter | 250mm |
| Angle of transverse feed | -30° |
Features:
Drive unit and gear head of the VD4HD/-30° are identical with the drive unit and gear head of the VD4HD Valve Seat Refacing Machine.
If a VD4HD is already on hand, only the D4/-30° adapter head is required for refacing the external conical landing face on valve cages.
The D4/-30° adapter head is bolted to the gear head in place of the seat refacing adapter head.
The pilot used for valve seat refacing can be also used for centering the VD4HD/-30°.
