At what PSI is air supplied to the vent damper actuator?

The vent damper actuator typically requires an air supply pressure within the range of 80-125 PSIG to ensure proper operation. This pressure range is essential for the actuation of the damper, allowing it to respond effectively to control signals and maintain the desired airflow within the gas turbine system.

Operating outside this pressure range can lead to improper function; pressures that are too low may not provide sufficient force for the actuator to open or close the vent damper adequately, while excessively high pressures could risk damaging the actuator or leading to erratic operation.

Understanding the specific pressure requirements for the vent damper actuator is crucial for maintaining the efficiency and reliability of the gas turbine system. This ensures that the actuator can effectively respond to the controller's commands, thus maintaining optimal performance and contributing to the overall health of the turbine operation.
