METSO D201134L

Description

Technical Specifications:

• Manufacturer: Metso (now Valmet/Neles)

• Product Type: 8-Channel Analog Input Module / Intelligent Valve Positioner

• Analog Input Channels: 8 channels

• Signal Types Supported: 4-20mA, 0-10V, J-type thermocouples

• Accuracy: 0.1% of full scale

• Response Time: 250ms

• Weight: 0.40 kg

• Country of Origin: USA

• Warranty: 12 months

Functional Features:

• High-accuracy signal conversion ensuring precise data acquisition from field devices

• Fast response time suitable for demanding applications

• User-friendly interface for easy installation and configuration

• Force balance principle combined with microprocessor control for dynamic position adjustment

Performance Parameters:

• Real-time comparison of control signal with actual valve stem position

• Dynamic regulation of output air pressure ensuring valve follows setpoint accurately

• Maintains stable regulation performance in high-temperature steam tracing, compressor vibration, or corrosive environments

Material Composition:

• Rugged industrial-grade housing suitable for harsh environments

Structural Characteristics:

• Stroke Adaptation: Linear stroke: 10–100 mm; Angular stroke: 20°–100° (via adjustable feedback arm)

• Mounting: Multi-directional rotating bracket, adaptable to ISO 5211 actuator mounting flanges

• Operating Temperature Range (Electronics): -40°C to +85°C

Working Principle: The positioning system operates on force balance principles integrated with microprocessor control. The microprocessor continuously compares the input control signal against the actual valve stem position feedback, dynamically adjusting the output air pressure to ensure the valve precisely follows the setpoint.

Advantages and Strengths:

• Resolves control performance degradation caused by wear, vibration, or temperature drift in traditional mechanical positioners

• Suitable for single-acting (spring return) or double-acting pneumatic actuators

• Direct replacement solution for aging Fisher 3580 or Siemens SIPART PS1 positioners

• 12-month functional quality warranty with key parameter test summaries

Applicable Industries:

• Oil refineries (hydrotreating units, reactor feed control valves)

• Chemical plants (polymerization reactor pressure/level control valves)

• Food and beverage, pharmaceutical, power generation

• Building automation (HVAC, lighting systems)

Model Series: Metso Valmet PLC Control Systems / Metso Automation Product Line

Installation Requirements:

• Installation must be performed by a qualified electrician

• Multi-directional rotating bracket mounting适配 ISO 5211 actuator mounting flanges

• DIN rail or panel mounting options available

Usage Precautions:

• Verify actuator type compatibility before installation

• Default configuration is single-acting; double-acting requires specific internal configuration

• Confirm compatibility with Metso Valmet PLC control systems only

• Not suitable for all applications; careful consideration of specific application needs required
