APPLICATIONThe QM/QF series of electric valve actuators are used in heating, ventilation, and air-conditioning (HVAC)applications. The QM series of electric valve actuators are modulating control actuators used with controls thatprovide an analog output of 0 to 10Vdc, 2 to 10Vdc or 4-20mA. The internal selector plug can be used to reversethe direction of action. The QF series of electric valve actuators are controlled by an on/off output.
