StG 2040/2080 Actuators
HEINZMANN's electric actuators do not require a mechanical drive and are easy to install on the motor
This powerful actuator is primarily designed for use with medium- and high-power gas engines.However, it can also be successfully used with gas engines or turbines.Features:High torque, with equal torque in both directions
Short actuation times
Low current consumption during load changes
Very low holding current
Insensitive to slow fluctuations in the power supply
Non-contact position feedback
Current limiting in case of mechanical blockage to prevent overheating
Can be installed in any orientation
Maintenance-free
Optional with return spring
Category: Controllers / Actuators, Gas Trains
Brand: HEINZMANN
