text: Most industrial dampers can be operated manually or automatically (through electric or pneumatic motors) but many can also be controlled – and the degree of air flow calibrated or adjusted – by a solenoid (a type of electromagnet) according to signals from the thermostat or other regulator going to the actuator of the damper in order to modulate the flow of air or gas.
