Zwick Triple Offset Sealed Bearings Eliminate Common Failures

1. The Problem Bearing failures are among the highest root causes of failure in triple offset valves (TOV) for tight shutoff applications. This issue is directly attributed to the need to have metal bearings with very tight tolerances when accepting the shaft diameter. Properly designed triple offset valves are metal to metal torque seated type valves. Therefore, very little shaft deflection can be tolerated in order to torque the seal ring into the seat. Additionally, properly designed TOV’s …
