Foxboro Eckardt BHNDMN6BDZNC Valve Positioner

Feature & Principle

It is Foxboro Eckardt SRD960 series flameproof intelligent electro-pneumatic valve positioner. It receives 4-20mA control signal from DCS and converts it into pneumatic output to drive valve actuator. It supports automatic startup and self-calibration, built-in comprehensive diagnostic functions including partial stroke test, friction analysis and valve signature. It adopts rugged Ex d explosion-proof housing, low air consumption and strong anti-vibration performance. It can be mounted on linear or rotary actuators following NAMUR and VDI/VDE standards.
