Product Short Description
Product Name: Metso ADC5483-D200136L Positioner / Valve Controller
Product Introduction: The ADC5483-D200136L is a smart valve positioner manufactured by Metso (formerly Neles, part of the Flow Control business). It is an electro-pneumatic positioner designed for precise control of rotary or linear control valves in process industries. The suffix “D200136L” identifies the specific configuration: digital HART protocol, 200 kPa supply range, 136 mm stroke variant, linear actuator.
Description
Technical Specifications:
- Type: Smart electro-pneumatic valve positioner

- Communication: HART 7 over 4–20 mA loop
Functional Features:
- Auto-calibration (initial and running)
- SIL 2 / SIL 3 capable (IEC 61508)
- Diagnostics: travel deviation, supply pressure, response time
- Partial stroke test (PST) capability
- Fail-safe action (spring-return or air-to-open/close)
Performance Parameters:
- Dead Band: <0.1% of stroke
- Response Time: <0.5 seconds (typical)
- Hysteresis: <0.15% of stroke
- Air Consumption: <12 Nl/min at 6 bar
Material Composition:
- Housing: Aluminum alloy (die-cast), epoxy-coated
- Internals: Stainless steel 316L, PTFE seals
- Cover: Polycarbonate with stainless steel fasteners
Structural Features: Top-mounted or side-mounted on actuator. Cable entry via 2 × M20 conduit entries. Weight approximately 4.5 kg.
Working Principle: The positioner receives a 4–20 mA signal from the DCS/PLC. It compares the valve’s actual position (measured by an internal LVDT or potentiometer) with the desired position and adjusts the output air pressure to the actuator until the valve reaches the correct position. HART communication allows remote configuration and diagnostics.
Key Advantages: SIL 2/3 certified for safety-critical applications. Full HART diagnostics enable predictive maintenance. ATEX-certified for hazardous areas.
Applicable Industries: Oil & gas, chemical, power generation, pulp & paper, mining, water treatment.
Model Series: Neles ADC5483 / Metso ND9000 Series smart positioners
Installation Requirements: Mount on actuator per IEC 60534-6. Supply air must be filtered, dry, and oil-free (ISO 8573-1 Class 1.4.1). Cable entry must be sealed with appropriate glands.
Usage Precautions: Verify SIL certification matches the safety function requirement. Perform initial calibration after installation. Do not operate without supply air filter.
