Motor-Operated Valve Technology and Services

Motor-Operated Valve Technology and Services

solutions to industry MOV problems

Kalsi Engineering provides comprehensive, industry-leading motor-operated valve (MOV) technology and services. For over 35 years Kalsi has developed and deployed value-added solutions to industry MOV problems including actuator thrust and torque rating extensions and cycle life evaluations, and, as a primary model developer for the Electric Power Research Institute (EPRI) MOV Performance Prediction Program, NRC-approved methods to determine operating requirements for gate, globe, and quarter-turn valves. Other MOV services include design-basis reviews and engineering evaluations to determine actuator torque and thrust output capability predictions, valve operating requirements, and actuator-to-valve interface capability.
