- Potential 10CFR Part 21 Report -
In late 1998 Enertech manufactured and shipped electro-hydraulic actuators for installation on valves to be installed in an overseas plant. Prior to shipment, the valve manufacturer observed pressure switch indication problems during final testing of the valves on which the actuators were installed.
Collective investigation by Burns and Roe, Enertech, including its switch supplier and the valve manufacturer determined the problem resulted from changes in manufacturing methods implemented by the switch supplier. The immediate problem was addressed, the pressure switches were modified using the supplier's previous manufacturing methods, installed on the valves and subsequently passed all final test requirements.
