Field Application and Mechanical Setup
Where is this actuator deployed? On a recent field retrofit for an emergency backup generator set, we utilized the 8256-016 to replace a sluggish hydraulic governor setup. Because this unit runs completely on electronic power, it eliminates the need for mechanical drive gears or dedicated oil lines.

[24 VDC Power Supply via 10A Fuse] Don’t overlook the physical mounting orientation of the housing block if the unit is installed outdoors. If the engine skid is exposed to weather elements, mounting the assembly with the clockwise serrated shaft end tilted higher prevents water pooling against the drive seal. Well, technically it delivers a robust 2.3 J of mechanical work, but only if the system battery charger supplies at least 5 A when the governor loops are fully energized. If you experience sudden engine hunting or unstable RPM control, avoid altering the linkages immediately. First verify the main power feed wire gauge; maximum wire runs must be kept under 11 m for 14 AWG lines to prevent critical voltage drops under transient load conditions.
International Trade and Customs Compliance
Shipping high-performance mechanical governor systems across borders requires strict regulatory adherence to avoid logistical bottlenecks. The export control classification number (ECCN) for this Woodward device is EAR99, allowing it to move to most global ports without a specific Department of Commerce export license, assuming standard denied-party screenings are cleared.
Our logistics operations handle international trade using EXW (Ex Works), FCA (Free Carrier), and CIP (Carriage and Insurance Paid) Incoterms. For critical generator failures or marine vessel shutdowns, express air routing via DHL or FedEx Priority guarantees arrival at your site within 48 to 72 hours. Every package leaves our dock with a complete commercial invoice, precise packing manifests, and the global harmonized tariff classification code (HS Code: 85011099) to expedite local import customs clearance. For major corporate procurement contracts, we support verified Letters of Credit (L/C) or secure wire transfers (T/T).
Frequently Asked Questions
Does this actuator include integrated electronic position feedback?
No. The 8256-016 model configuration does not include internal position feedback sensors. It relies strictly on proportional current loops driven by your external EPG speed control card.
Can this unit be used for synchronized, multi-generator load sharing?
Yes. While the actuator executes the physical movement, it can be paired with appropriate speed control units and external load-sharing modules to handle parallel generator configurations.
