Maximum Allowable Stem Torque (MAST)
MAST (Maximum Allowable Stem Torque) We know ball valves (rotary valves) are used as ESDVs/BDVs in critical services like shutdown, isolation and blow down appliion.. As an engineer we always ensure reliability and integrity of actuator and its components. However as far as stem components are concerned we either give little attention to mechanical integrity of stem or sometimes .

Detent Torque and Holding Torque: What's the difference?
· Holding torque is typically higher than running torque, and is limited primarily by the maximum current the motor can withstand. From a practical standpoint, holding torque is the sum of the magnetic force exerted by the coils to hold the motor's current position, plus the detent torque. Once the motor is moving, the torque available at low ...
