WOODWARD 8404-213 Actuator

The WOODWARD 8404 - 213 actuator is a device with a variety of features and functions, as described below:

Features and Functions

Fast Bidirectional Drive: It is an extremely fast bidirectional electric actuator that can be electronically positioned in both directions, can respond quickly to control signals, and achieve precise position control.

No external drive or hydraulic supply required: The all-electric design does not require additional drive devices or hydraulic systems, which simplifies the installation and maintenance process and reduces the complexity and cost of the system.

Integrated drive: The integrated drive is suitable for speed control or positioning tasks of reciprocating engines, and can be directly connected to the engine's control system to achieve precise control of engine speed or other parameters.

Large Angle Rotation Output: The 75° (±2°) rotation output angle allows direct coupling with devices such as butterfly valves, without the need for complex linkage mechanisms, reducing errors and wear in the transmission links, and improving the accuracy and reliability of control.

Wide Application Range: There are four actuator sizes that can adapt to a wide range of application scenarios, and with configurable parameters, it can be customized according to different application requirements to meet the requirements of various industrial process control.

With advanced diagnostic functions: With advanced diagnostic functions, the actuator can monitor the operating status of the actuator in real time, detect faults in time and alarm, which helps to quickly troubleshoot, reduce downtime, and improve system reliability and maintainability.

Comply with relevant standards: It meets CE compliance standards such as EMC (electromagnetic compatibility) and the Machinery Directive, is suitable for CSA Class I, Division 2, Groups A, B, C, and D areas in Canada and the United States or only for non-hazardous locations, and has a 3R type rainproof enclosure for use in harsh environmental conditions.
