Intrusive Quarter-Turn Actuators – LTQ 

The Limitorque LTQ compact, quarter-turn electric actuator delivers superior reliability and performance through its industry-proven epicyclic locking gear set design. It is ideal for applications that require a simplistic, non-networked and cost-effective quarter-turn actuator that has analog controls, torque switches, limit switches, and discrete position feedback capabilities. The limit and torque switches, standard controls and a wide range of output offerings allow a higher degree of customization that can meet exacting customer needs.
