Supertech valves are manufactured from a forged part which is then CNC machined for optimal precision. They then receive a heat treatment (which varies depending on the valve's application) and are ground again (super-finishing process). Supertech valves are checked by several means such as ultrasound, X-rays and laser measurement.

For more than three decades, Supertech has worked to find the most suitable materials for each valve and each application in order to increase reliability. There are therefore different valve materials such as stainless steel, Inconel, titanium and sodium (the latter is present in the valve stem and allows better heat dissipation).

Catcams' expertise on camshafts and their accessories (valve springs, mechanical followers, adjustable pulleys, etc.) has been recognised worldwide for many years thanks to its know-how and precise study of engines and applications. Each camshaft profile and spring rate has been developed according to the specifics of each engine, as well as its use (road, sport, rally, sprint, circuit, etc.).
