WOODWARD 8200-513

الوصف

The WOODWARD 8200-513 is a Digital Valve Positioner (DVP), an essential electronic device for precisely controlling valves and actuators in industrial gas and steam turbine applications.

WOODWARD 8200-513: Digital Valve Positioner (DVP)

The WOODWARD 8200-513 DVP is designed to translate control signals from a main turbine control system into accurate movements of a connected valve or actuator. This allows for highly precise and dynamic control over critical parameters like fuel flow, steam flow, or other process variables, ensuring efficient and stable turbine operation.

Product Overview

This particular part number represents a specific configuration within Woodward’s advanced DVP series, built for robust performance and flexibility in demanding industrial environments.

• Product Type: Digital Valve Positioner (DVP) / Electric Actuator Driver
• Manufacturer: Woodward
• Part Number: 8200-513
• Key Specifications (based on Woodward’s product information and typical DVP configurations):
  • Input Power: 24 VDC (typically in the range of 18–36 VDC).
  • Ingress Protection (IP) Rating: IP66, indicating robust protection against dust ingress and strong jets of water. This makes it suitable for more exposed industrial environments compared to lower IP ratings.
  • Input/Output Connections: Features Conduit Input/Output, meaning electrical wiring connections are made via conduits, offering enhanced protection for the wiring in harsh conditions.
  • Communication: As part of the DVP series, it supports various communication protocols, including analog inputs, PWM, and often CANopen, and potentially Ethernet depending on specific module options.
• Function: The 8200-513 DVP receives a demand signal from a turbine controller (such as a Woodward MicroNet or 505 controller). It then uses this signal, along with high-resolution position feedback from the valve or actuator (typically via a resolver), to precisely drive the valve to the commanded position. It contains a robust internal controller that employs advanced algorithms (e.g., PID, OptiTune adaptive PID) to ensure high-speed, precise, and stable valve control, crucial for maintaining turbine stability and performance during all operating conditions.

Detailed Product Description

The Woodward 8200-513 Digital Valve Positioner is a state-of-the-art driver for Woodward’s electric actuation systems. Its design emphasizes accuracy, responsiveness, and reliability, making it suitable for modern turbine control applications.

• High-Speed, Precise Control: The DVP utilizes advanced control algorithms and high-speed processing to accurately and rapidly position valves and actuators. This dynamic response is crucial for stable turbine operation, especially during transients like load changes, startup, and shutdown.
• Integrated Control Architecture: It leverages Woodward’s latest control architecture, offering robust control for various motor types, including Limited Angle Torque (LAT) and Brushless DC (BLDC) motors found in Woodward’s high-performance valves and actuators.
• Resolver Feedback for Accuracy: The DVP relies on resolver feedback from the valve or actuator to determine its exact position, creating a highly accurate closed-loop control system that ensures high repeatability and minimal overshoot.
• ID Module Compatibility: Many newer Woodward valves and actuators come with an integrated “ID module.” When connected to such a device, the 8200-513 DVP can automatically read critical valve-specific configuration information, enabling a “plug-and-play” installation and simplifying setup and commissioning.
• Robust IP66 Enclosure: The IP66 rating signifies that this DVP is highly protected against dust and powerful water jets, making it suitable for direct installation in more challenging industrial environments without requiring an additional protective enclosure.
• Conduit Connections: The use of conduit for input and output wiring further enhances protection against environmental factors and physical damage, providing a very robust electrical connection method.

Typical Applications

The WOODWARD 8200-513 Digital Valve Positioner is a core component in:

• Gas Turbine Fuel Control Systems: Precisely positioning gas fuel metering valves to control combustion processes in a wide range of industrial settings.
• Steam Turbine Valve Actuation: Driving steam admission, extraction, or bypass valves for speed, load, and pressure control. Its IP66 rating makes it suitable for steam turbine decks where moisture or washdowns might occur.
• Compressor and Pump Control: Utilized in systems where highly accurate and dynamic positioning of control valves is necessary to regulate flow, pressure, or other process variables in industrial machinery, especially in harsh environments.
