We forge our valves using electro upsetting technology with an automatic loading and unloading system with Pyrometers to check the temperature of the bulb during the forming operation of the head. To machine our engine valves we use CNC lathes and CNC grinding machines allowing our products to respect the more tight production tolerances of o.e. manufacturers.
We laser mark each of our engine valves to guarantee the traceability of our products also after working in the engine.
