    SUPERTECH valves start life as a forging, which is then CNC machined for the closest possible accuracy. They are heat treated, the treatment varying with the intended use of the valve, then ground again in a super-finishing process. SUPERTECH valves are inspected by several methods, 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. Hence the different valve materials: stainless steel, INCONEL, titanium and sodium, the latter being contained in the valve stem to improve heat dissipation.
