Supertech Valves are manufactured from a forged part which is then CNC machined for optimal precision. They then receive a Thermal Treatment (different depending on the application of the Valve) and are ground again (Super-finishing Process). The Supertech Valves are controlled by different means such as Ultrasound, X-rays, laser measurement.

For more than three decades, Supertech has strived 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, sodium (the latter is present in the valve stem and allows better heat dissipation).
