Valve Seat Remover / MPI
Induction system that removes worn valve seats from cylinder heads without welding, force or open flame; seats heat in about 15 seconds.
Description
The MPI system, designed by Chris-Marine Denmark, removes worn valve seats from cylinder heads without welding, force or open flame. A high-frequency induction generator feeds a water-cooled, insulated induction coil centred on the valve guide, heating the seat rapidly while the cylinder head stays cool.
Key features
- Seat heated typically in 15 seconds
- After cooling the seat diameter contracts by 0.3 to 0.5 mm for easy, non-destructive removal
- Minimises damage to the seat recess
- Hydraulic Valve Seat Remover (VSR) also offered, with tool heads for 44 to 140 mm seats at 250 bar
Applications
- Valve seat replacement in cylinder head overhaul
