8402-271 Woodward High-performance Digital Speed Governing Controller
8402-271 Woodward high-performance digital speed governing controller
The Woodward 8402-271 is an electronic actuator manufactured by Woodward Corporation, an American company. Woodward is a leader in energy control and optimization solutions, and its products are widely used in aviation, power generation, power distribution, and other fields.
Functions: Potentially used for the control and monitoring of industrial turbines, turbine generators, and turbine expanders, featuring speed and load control, system optimization, real-time data monitoring, and fault diagnosis.
Technical Characteristics: May employ digital microprocessor technology, supporting field programming and flexible configuration. Equipped with a communication interface, supporting protocols such as Modbus, and capable of interoperating with DCS/PLC systems.
Physical Specifications: Operating temperature may range from -10°C to approximately 60°C. High protection level, with vibration and shock resistant design.
The SOGAV must always close sufficiently before the air inlet valve closes in order to assure that all gas admitted into the inlet runner gets carried into the combustion chamber. If this time is not sufficient, gas will remain in the inlet runner after the intake valve closes and will pass through to the exhaust during the next overlap period (wasting fuel and emitting unburned hydrocarbons). It is the responsibility of the engineer applying the SOGAV system to determine the timing of SOGAV opening as well as the maximum allowable duration.

Product Selection and Customization Instructions
Selection Basis: The selection must be based on parameters such as on-site pneumatic circuit pressure, flow rate, control voltage, media type, and installation space to match the corresponding 8402-271 product specifications.
Customization Options: Supports customization of interface specifications (G/NPT/Metric), reset mode (normally closed/normally open), voltage specifications (24V DC/110V AC/220V AC), corrosion resistance level, etc., to adapt to special industrial scenarios.
Same Series Alternatives: If no compatible specification is available for 8402-271, refer to other models in the 8402 series (such as 8402-119, 8402-319). The core control characteristics are the same, with only minor differences in parameter details.
