valve(ball valve, motorized Valve)

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 10Vdc, 2 to 10Vdc or 4-20mA. 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. FEATURES l Low power consumption l Position feedback by signal l Direct/reverse acting l 4-20mA/0-10V/2-10V choice l Maintenance free l Quick and easy installation l No separate linkage required l Accurate valve positioning l Indicator Continuous Position Indicator l Manual Override Non-clutch design l Gear Permanently lubricated and self locking l Stall Protection Built-in thermal protection
