SUPERTECH valves are made from a forging which is then CNC machined for optimum precision. They then undergo heat treatment, which varies with the valve application, and are ground again (Super-finishing process). SUPERTECH valves are inspected by various means including ultrasound, X-ray and laser measurement.

For more than three decades SUPERTECH has worked to find the most suitable material for each valve and each application in order to improve reliability. Valves are therefore available in different materials such as stainless steel, Inconel, titanium and sodium, the latter sitting inside the valve stem to give better heat dissipation.
