5464-439 Woodward Ship Spare Parts

The 5464-439 is a microprocessor-based digital governor controller produced by Woodward, belonging to its classic 505 series.
It is primarily designed for speed control and protection of steam turbines. Below is a detailed introduction to this product:

I. Product Overview

Brand and Model: Woodward 5464-439
Series: 505 Series Digital Governor
Type: Microprocessor-based controller
Purpose: Specifically designed for steam turbines to control their speed and provide overspeed protection.

II. Core Functions

Speed Control:
- 5464-439 Precisely controls the speed of steam turbines by adjusting steam inlet flow.
- Supports single-range or split-range actuators to accommodate turbines of different sizes.
Overspeed Protection:
- Incorporates triple independent overspeed protection logic to ensure rapid shutdown in case of overspeed, preventing equipment damage.
- Provides an overspeed test button for convenient on-site testing of protection functions.
Emergency Shutdown:
- Equipped with an emergency stop button for immediate shutdown in emergency situations.
System Protection:
- - Automatically switches control modes upon sensor failure to ensure uninterrupted system operation.
  - Offers local/remote control priority selection to adapt to different operational scenarios.

Function of pressure controller
Pressure controllers can be used for neutral or corrosive gas and liquid media. The set value range is adjustable, with an adjustment range of 0.02~42Mpa. The switching

difference is not adjustable. The pressure controller includes a wide range and many varieties, including differential pressure controller, explosion-proof pressure switch,

explosion-proof differential pressure switch, pressure transmitter, differential pressure transmitter, wind pressure switch, and wind pressure transmitter.

The function of a pressure controller is to detect, display, alarm, and control signal output to ensure the normal operation of the system. It collects and processes data through

a high-speed MCU and has built-in precision sensors for compensation. It is a high-precision device that detects pressure and liquid level signals, achieves pressure and

liquid level monitoring and control. Widely used in automation systems for measuring

gas and liquid pressure in chemical, mechanical, hydrological, electrical, environmental, and other fields. Due to its convenient and flexible adjustment, as well as simple

installation, it can replace most situations where liquid level switches are used.

With the continuous development of technology, pressure controllers, as an emerging technological force, have occupied the pressure control market and become a strategic

requirement for the development of China”s industry. They are not only suitable for industrial petroleum and coal mines, but also begin to appear in modern household appliances.

It can be seen that pressure controllers are becoming increasingly important.

Pressure controller is mainly a type of pressure control product, which plays a role in timely controlling pressure and controlling the start and stop status of equipment in industry,

agriculture, and modern life. Take the familiar boiler as an example. A boiler is a relatively dangerous energy equipment. Once its pressure is not controlled, the accident rate is very high.

The pressure controller plays an irreplaceable role inside. When the boiler pressure reaches the rated value, the pressure controller will control the boiler to stop working in a timely manner.

When the pressure returns to the safe pressure value, the boiler will restart working.
