SUPERTECH valves are made from a forging which is then CNC machined for optimum precision. They then receive a heat treatment, which varies with the valve application, and are ground again (Super-finishing process). SUPERTECH valves are inspected by various 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 several valve materials such as stainless steel, Inconel, titanium and sodium, the latter being contained in the valve stem to allow better heat dissipation.
