Valve seat

Valve seat grinding wheels are specially designed abrasive tools used to accurately grind and resurface the valve seats in internal combustion engines. These wheels ensure a precise seal between the valve and the seat, which is critical for maintaining compression, performance, and engine efficiency.

Key Features:

• precision and consistency for perfect valve-to-seat sealing

Available in a range of abrasives:

• Silicon carbide – for cast iron seats

• Aluminum oxide – for hardened steel seats

• CBN and diamond – for extremely hard or alloyed materials

• Various sizes and angles (usually 30°, 45°, and 60°) to match OEM specifications

• Compatible with both manual and automated seat grinding machines

Applications:

• Automotive engine rebuilding

• Aircraft, marine, and industrial engine maintenance

• Performance engine tuning and racing applications

Valve seat grinding wheels are essential tools for ensuring tight seals, minimizing blow-by, and optimizing combustion efficiency in any engine that relies on precision valve seating.
