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. FEATURES l Low power consumption l Position feedback by signal l Direct/reverse acting l ***0mA/***0V/***0V 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 TECHNICAL DATA: VALVE Flow media Cold and hot water, water with max. *0% volume of glycol Temperature of medium **0?xxxxx ***0?C Rated pressure ***0 / ***0kPa Leakage rate Air bubble-tight (Bo 1, DIN ***0) Closing pressure ***0kPa Size DN**-DN**0 Material Body Cast copper or Stainless Steel , Shaft Stainless Steel, Actuator Actuator QF/QM Output torque *0, *6, *5, xxxxx Power supply AC**0V or AC/DC*4V Run time About **0S Operating power 5VA Output angle *0?? 3?
