DT DigitalTrack Positioner is a loop powered instrument. As a control part of the pneumatic valve set, this positioner is widely used in petroleum, chemical, electric generation, metal production, light industry and other fields of automation systems.

This product accepts 4-20 mA valve setting signal from the control system; at the same time, it receives the actual valve signal through the local sensors. The two signals are compared by control software in order to control the feeding to the actuator and the exhaust from the actuator, driving the valve to reach the set point. It can overcome friction and the imbalance power on the control valve, and improve the response speed of the control valve. Thus, it can reach the required position rapidly and accurately.
