The Mark 708MV offers several advantages including extreme accuracy, high turndown ratios and repeatability. The features of his high resolution, low hysteresis digitally controlled motor makes the MK708MV a premiere control valve for applications involving chemical injection, dosing, pilot plants and research labs. In addition, it is a prime valve for skid builders. Additional features of the MK708MV include a switch-selectable power supply, a handwheel for manual operation and a 4-20 mA or split range current input signal. 0-5 or 0-10 VDC voltage signal, 4-20mA feedback, and various protective enclosure classes are standard features on these motors. Upon loss of input (not loss of power), the motor is designed to either lock in place, or fail to minimum input signal position.
