The MG900 SR is a linear eletro-mechanicl actuator with spring return operation for the control of two-way and three way globe valves. The family of actuators utilise brushless DC motors and a high resolution control board allow a very fine fluid control in globe valves. The working range and end point switches of the actuator are adjusted automatically to the stroke of the valve. When driven electrically, the fimware of the actuator calibrates a consistent running time regardless of the valve stroke. Spring return stem up (retract). Supply Voltage: 24 Vac. Force nomina: 900 N, enclosure rating: IP54. Position Feedback Output Signal: 2…10 Vdc, 0…5 Vdc. Stroke: 9-32 mm. Circuit board.
