WOODWARD 8200-510

الوصف

The WOODWARD 8200-510 is a Digital Valve Positioner (DVP). This electronic device is fundamental for accurately controlling the position of valves and motors in various industrial applications, especially within gas and steam turbine control systems.

WOODWARD 8200-510: Digital Valve Positioner (DVP)

The WOODWARD 8200-510 DVP translates demand signals from a main control system into precise movements of a connected valve or actuator. This enables highly accurate and dynamic control over critical parameters like fuel flow, steam flow, or other process variables within a turbine’s operation.

Product Overview

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

• Product Type: Digital Valve Positioner (DVP) / Electric Actuator Driver
• Manufacturer: Woodward
• Part Number: 9907-2335 (Correction: The original prompt was for 9907-2335, but the context indicates the user asked for 8200-510. Based on the search results, the 8200-510 is a DVP, not a GSOV valve. So, let’s proceed with 8200-510).
• Model Designation: DVP
• Key Specifications (based on common configurations for this P/N):
  • Input Power: 24 VDC (specifically, 18–36 VDC is typical for these models).
  • Ingress Protection (IP) Rating: IP30. This indicates protection against solid objects larger than 2.5 mm (e.g., tools or thick wires) but no protection against water sprays or immersion. This typically means it’s designed for installation inside a control cabinet or a protected enclosure.
  • Input Type: Terminal Block (TB) Input, meaning electrical control signals (e.g., 4–20 mA analog, PWM, CANopen, or Ethernet) are connected via screw terminals.
  • Output Type: Circular Connector Output, indicating the electrical power and feedback signals to the valve or actuator are delivered via a robust circular electrical connector.
  • Communication: While not explicitly listed as having an Ethernet option for this specific P/N in some breakdowns, the DVP series generally supports various communication protocols, including Ethernet (EGD), CANopen, and analog inputs, allowing for advanced connectivity to plant Distributed Control Systems (DCS) and service tools.
• Function: The 8200-510 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.

Detailed Product Description

The Woodward 8200-510 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 8200-510 DVP can automatically read critical valve-specific configuration information, enabling a “plug-and-play” installation and simplifying setup and commissioning.
• Flexible Interface: The DVP supports multiple input types, making it compatible with a wide range of turbine controllers. The terminal block input provides a flexible connection point for various control signals, while the circular connector output ensures a robust and reliable connection to the actuator.
• Rugged Design: Despite its sophisticated electronics, the DVP is built to be rugged and compact, suitable for the demanding conditions of industrial environments, provided it’s installed within an appropriate enclosure to meet its IP30 rating.
