Description
Flowserve Logix 520MD Plus Digital HART Valve Positioner
Product Overview
  1. Adopts advanced piezoelectric technology with 4–20mA two-wire HART 5/6/7 communication for valve actuator control.
  2. Built-in over 130 valve diagnostic alarms, supporting ValveSight DTM software for real equipment health monitoring.
  3. Supports on-site quick auto-calibration and local jog operation without handheld communicator.
Technical Specifications
Category Official Standard Parameters
Input Signal 4–20mA DC, HART protocol; loop voltage ≥10VDC, max 500Ω load
Air Supply 1.5–6.2 bar; air quality meets ISA 7.0.01 standard.
Control Performance Linearity <±1.0%; resolution <0.1%; fast startup within 1 second
Environment Standard temp: -20℃~+80℃; IP67 housing; ATEX / FM intrinsically safe certification
Software & Hardware Local LCD & LED indicator; single/double acting actuator compatible; 10-year service life
Application Industry
  1. Oil & gas upstream/downstream pipelines for pneumatic regulating valve automatic control
  2. Chemical & petrochemical plants for corrosive medium flow adjustment valves
  3. Thermal power station boiler and steam pipeline control valve matching equipment
Common Problems & Solutions
  1. Control loop oscillation: Reduce proportional gain, clean internal spool valve and filter air supply.
  2. Position feedback failure: Check linkage connection, execute full stroke quick calibration.
  3. HART communication loss: Verify loop voltage and wiring, restart device after power cycle.
Replacement Models
  1. Flowserve Logix 521MD Plus / 522MD Plus high-end upgraded positioners
  2. Flowserve Logix 3200MD series double-acting digital HART positioner
  3. Masoneilan SVI2 AP universal HART valve positioner cross-brand substitute

  1. Supply brand-new original Flowserve complete sets with factory test & explosion-proof certificates.
  2. Provide free calibration guidance and ValveSight DTM software operation training.
  3. 12-month official warranty with global after-sales technical support service.
Stock & Delivery Time
  1. Standard non-explosion Logix 520MD Plus models in stock, ship within 3–7 working days.
  2. Custom intrinsically safe ATEX/FM versions take 15–20 working days for production.
  3. Complete export customs documents provided for sea & air global logistics.
RFQ Form
  1. Specify explosion-proof grade and single/double acting actuator matching requirement.
  2. Confirm valve stroke range and working temperature environment parameters.
  3. Inform target order quantity to get accurate FOB USD tiered unit price.
