Product Description
Flowserve Logix 520MD
The cheapest way to go digital without losing reliability
Why Plants Use 520MD When Budget Is Tight
The 520MD is the baby brother in the Logix family. It has the same basic auto-tune and LED display as the bigger ones but costs less. Plants use it on water valves, air dampers, and non-critical loops where they want digital features but can’t justify the full 3800 price. It still beats any pneumatic positioner on stability and air savings.
Budget-Friendly Goodies
- Simple LED status lights – green good, red bad
- Quick-cal button – sets up in 30 seconds
- 4–20 mA input, no HART – keeps cost down
- Compact aluminum housing
- Same mounting as 3800 – easy upgrade path
- Low bleed – pays for itself in air savings
