Woodward 8400-016 Electrically Powered Governor (EPG) — Industrial-Grade Speed Control, 100% Original

As a Procurement Manager sourcing critical spare parts for industrial automation systems, you need components that are verified original, immediately available, and backed by real technical support. The Woodward 8400-016 Electrically Powered Governor (EPG) is a 100% Brand New and Factory Sealed actuator designed for precision speed regulation of diesel and gas engines across heavy-duty industrial environments. This Woodward 8400-016 unit is an Original New spare part — not refurbished, not remanufactured — sourced directly to meet the stringent demands of PLC System integrators and plant engineers worldwide.

In facilities where unplanned downtime translates directly to lost revenue, the 8400-016 eliminates the mechanical wear points inherent in legacy flyweight governors. Its closed-loop electronic feedback architecture maintains ±0.25% speed regulation under dynamic load swings, making it the preferred Control Module for power generation, marine propulsion, and industrial drive applications. Whether you are maintaining an aging DCS infrastructure or commissioning a new Industrial Automation cell, this EPG actuator delivers the reliability your operation demands.

We stock the Woodward 8400-016 for immediate dispatch. Contact our team today for a competitive quote and lead-time confirmation.

Technical Specifications & Selection Guide

Selection Tip: If your application requires greater rotational travel (>30°) or higher torque output, consult our engineering team for alternative Woodward EPG models. The 8400-016 is optimized for medium-duty diesel and gas engine governor applications in the 50 kW 3 MW range.

Typical Application Scenarios

Power Generation & Diesel Gensets: Diesel generator sets in remote mining camps, data centers, and utility substations demand rock-solid frequency stability. The Woodward 8400-016 maintains precise RPM under load transients, enabling stable parallel operation and load sharing without hunting or oscillation.

✅ Oil & Gas Processing: Compressor drivers and pump packages on upstream and midstream facilities operate in hazardous, high-vibration environments. The IP65-rated, heavy-duty construction of the 8400-016 withstands these conditions while delivering the precision throttle control required by SIS safety logic solvers.

✅ Marine Propulsion & Auxiliary Systems: Commercial vessels and offshore platforms rely on auxiliary engine governors that meet SOLAS and classification society standards. The robust SAE flange mounting of the 8400-016 enables direct retrofit on existing engine installations with minimal downtime.

✅ Industrial Drive Systems: Mechanical drive applications — including gas compressors, irrigation pumps, and industrial fans — benefit from the 8400-016’s electronic precision, replacing wear-prone mechanical governors and reducing maintenance intervals significantly.

Power Plants & Cogeneration: In combined heat and power (CHP) plants, the 8400-016 integrates seamlessly with Woodward digital controllers (505E, easYgen series) via Modbus RTU or CANopen, enabling advanced droop compensation and remote setpoint adjustment from the DCS or PLC System control room.

FAQ — Frequently Asked Questions

Q1: What is the price of the Woodward 8400-016, and do you offer volume discounts?
A: Pricing for the 8400-016 is competitive and varies based on order quantity and delivery urgency. We offer tiered volume discounts for orders of 3 units or more. Please contact sale@ninermas.com with your required quantity and delivery timeline for a formal quotation within 24 hours.

Q2: What is the lead time for the Woodward 8400-016?
A: In-stock units ship within 1-2 business days via express courier. For larger quantities or special configurations, lead time is typically 3-7 business days. We maintain safety stock of high-demand Woodward Industrial Automation spare parts to support emergency procurement needs.

Q3: Can you provide a Datasheet or technical documentation for the 8400-016?
A: Yes. The official Woodward 8400-016 datasheet, installation manual, and wiring diagram are available upon request. Contact our technical team at sale@ninermas.com and reference model 8400-016 in your inquiry.

Q4: Is the 8400-016 compatible with Woodward 505E and easYgen digital controllers?
A: Confirmed. The Woodward 8400-016 is fully compatible with the 505E speed controller and the easYgen genset controller series. It communicates via standard 4-20 mA analog interface and supports Modbus RTU integration when paired with appropriate signal conditioning modules.

Q5: How do I verify the unit is 100% Original and Brand New?
A: Every 8400-016 unit we supply is 100% Original and Brand New, shipped in original Woodward factory packaging with intact tamper-evident seals.
