Induction Valve Seat Removal (IVSR) Systems

Non-contact, Flameless Induction Valve Seat Removal (IVSR) and Powertrain Reman Systems

Ajax TOCCO Magnethermic’s IVSR systems have revolutionized heavy-duty engine remanufacturing operations, specifically in the time-consuming task of removing pressed-in valve seats from engine cylinder heads. Ajax TOCCO’s IVSR process has increased the profitability of engine reman facilities globally, while simultaneously increasing quality, efficiency, core retention rates, operator safety, and ergonomics. Our IVSR technology is so effective, valve seats can be easily removed with minimal force, saving valuable time and money. By way of induction, valve seats are heated and cooled in seconds, resulting in the mechanical shrinking of the pressed-in seats. No subsequent machining is needed for valve seats or seat recesses, which means the valve seats can be replaced over and over, extending the life of the cylinder head.
