Siemens SQM50.461R1G3 Control Valve Actuator

Siemens SQM50.461R1G3 Actuator, 140 in-lb torque, 25 seconds running time for 90 Degree rotation (30 secs run time if 50 Hz), 6 Switches, round 10 mm single ended Shaft, 110 Vac, 4-20 mA Input, 1000 Ohm, 90 Degree Potentiometer, CCW. UL and CSA Approvals.

SQM5... reversing actuators are used for the positioning of flow control valves, butterfly valves, dampers, or any application requiring rotary motion. The SQM5… actuators accommodate control input signals of 4 to 20 mA, 0 to 135 Ohms, 0 to 10 Vdc, 0 to 20 mA, position proportional and floating control. The available output signals include 4 to 20 mA, 0 to 135 Ohms, 0 to 10 Vdc, 0 to 20 mA, and 0 to 1000 Ohms. SQM5… actuators are available with up to six internal, easily adjustable switches.

A selection of exchangeable circuit boards provide a variety of functions including auto/manual selector switch, manual forward/reverse toggle switch, zero and span adjustment, parallel or master/slave operation, split range control, input signal override, and selectable electronic linearization.

The SQM5… is engineered for precision. It is particularly well suited for applications requiring a high degree of modulating accuracy and repeatability.

The SQM5… actuator may be mounted in any position. A selection of mounting brackets and shafts provides installation flexibility and allows for the simple replacement of most competitive actuators.
