SUPERTECH valves are manufactured from a forged part which is then CNC machined for optimal precision. They then receive a heat treatment (different depending on the application of the valve) and are ground again (Super-finishing process). SUPERTECH valves are controlled by different means such as ultrasound, There are therefore different valve materials such as stainless steel, inconel, titanium, sodium (the latter is present in the valve stem and allows better heat dissipation).
