Fatigue assessment of scotch yoke for high cycles applications in heavy-duty valves actuators[R]

Actuator life-span is typically measured in cycles of operations – cycle life.

Many flow-control processes require on-off valves and actuators to cycle with great
frequency, meaning a reduced temporal lifespan and increased maintenance intervals.

Very often valves and actuators cycle life is based on estimation or field history and is not validated rigorous experimental evidence.
