APPLICATION 
The 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 that 
provide an analog output of 0 to *0Vdc, 2 to *0Vdc or ***0mA. The internal selector plug can be used to reverse 
the direction of action. The QF series of electric valve actuators are controlled by an on/off output.
