The torque limiter for modec portable valve actuators means you can disconnect the motor section from the gear box section when the torque limit is reached. No torque is thereafter applied by the actuator.

The operator can set the torque limit within a +/- 40% range of the original value. The torque limiter option is available for the HL83S and H models, as well as for the PY68 and JA73S and H models (the JA73E models have a torque limiter in series).
