Electric Damper Actuator is a kind of actuator mechanism driven by electric power, which is 90 ° angle travel actuator. The  provided by Jifeng technology include on-off volume air valve actuators, analog volume air valve actuators, fast-acting type air valve actuators and spring-reset type air valve actuators

is used for Electric Control Air Valve, widely used in heating, ventilation, air conditioning, refrigeration and other building automation systems. JIFENG technology provides electric air valve actuator voltage 12V, 24V, 110V, 220V and so on. We Provide 24V actuator switch analog quantity, which is three terminals, 1 for the common terminal, 2,3 for the positive. Analog quantity is 5 terminals, of which 1,2 for 24V power supply, 3 is the signal negative pole, 4 is the signal input, 5 is the signal feedback. Similarly we provide 220V actuator also has the switch analog, 220V switch control mode is 1 terminal for the Common Terminal (generally zero line) , 2,3 terminal generally for the fire line. 220V analog control mode is 1,2 terminals is 220V power supply, 3 terminal is the signal negative pole, 4 is the signal positive pole, 5 is the signal feedback.
