Positioners > Mark 15 Series




![]() |
The Mark 15 positioner uses the full force of its air supply to drive and maintain the piston or diaphragm in a pneumatic actuator to position a valve to what is required by control instrument, regardless of the presence of forces that change valve position. The MK15 has feedback circuits designed to measure the position of the actuator's piston or diaphragm. The positioner then supplies or exhausts air to bring the actuator within the required range for its corresponding control instrument. |
