Specifications vary based on configuration and actuator type.
The Flowserve Logix 520MD receives a 4–20 mA command signal from the process control system. Its internal electronics compare the command with valve position feedback and modulate pneumatic output to move the actuator to the required position. Through HART communication, field technicians can perform configuration, tuning, diagnostics, and remote troubleshooting without removing the device from service.
Yes, with the appropriate mounting hardware it supports rotary actuators.
Yes, the modular design and HART support make it suitable for retrofit upgrades.
Yes, digital diagnostics and remote monitoring are available via HART.
The 520MD offers extended functionality and performance upgrades over earlier MD-series models.
HART communication can be used with standard field configuration tools.
