The starting torque is likely to be to times the full load torque. Induction motors can be started directly online using a DOL starter which generally consists of a contactor and a motor protection equipment such as a circuit breaker. A DOL starter consists of a coil operated contactor which can be controlled by start and stop push ...

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 .
