Product Introduction :
BDP7 intelligent valve positioner is a two-wire field instrument launched by Beary. As a pneumatic valve control component, the product is widely used in petroleum, chemical, electric power, Metallurgy, light industry and other automatic control fields.
The BDP7 intelligent valve positioner receives the 4-20mA valve position setting signal from the control system and obtains the actual valve position signal through the sensor.
The two are processed and then the air intake and exhaust of the actuator are controlled, and finally the valve is driven to the set position. (As shown in the figure)
BDP7 intelligent valve positioner is a high-performance electric/pneumatic valve positioner based on microprocessor technology, which can effectively overcome the friction and unbalanced force on the valve core.
Improve the response speed of the control valve and position it quickly and accurately.
Adaptive function: automatically determine the valve zero point and full scale, optimize valve control parameters, and improve control accuracy
Configuration function: can set valve characteristic curve, action mode, dead zone, travel range, event output
Self-diagnosis function: can display input current, up/down travel time, dead zone
Fault mode: When a fault occurs, the positioner can choose to maintain, fully open or fully closed mode
Position feedback function: output 4-20mA DC valve position feedback signal
