A case study was completed on a 400mm NB Pinch Valve that was trialed at Sibanye Stillwater’s Dam 20 re-mining site. The purpose of the trial was to test if the Red Roc pinch valve would operate successfully for a duration of six months. Upon the successful completion of that trial Sibanye Stillwater would consider using the Red-Roc pinch valve in similar applications. After six months the valve stood up well to the harsh operating conditions it was subjected to and it was not necessary to remove it from the line for maintenance. Sibanye Stillwater has installed another four valves on that site.
