Woodward UG-10 Governor

by | Nov 17, 2025 | INSIGHT

A high-output mechanical-hydraulic governor delivering precise, stable speed control for diesel/gas engines and steam turbines. With 15.9 N·m output and 150 psi pressure, it’s a reliable choice for marine and power-generation use. We offer UG-10 supply, overhaul and calibration services.

Woodward UG-10 Governor

The Woodward UG-10 governor is a high-work-output mechanical-hydraulic governor designed for precise speed control of diesel, gas and dual-fuel engines, as well as steam turbines in marine and power-generation applications.

Woodward UG-10 Governor – Features & Technical Overview

The UG-10 is part of Woodward’s proven UG governor family and shares the same robust construction and mounting footprint as the UG-5.7 and UG-8, while delivering higher work output for demanding applications.

Key technical characteristics (UG-10):

  • Mechanical-hydraulic governor for control of diesel, gas and dual-fuel engines, and steam turbines
  • High work output: approx. 15.9 N·m (11.7 lb-ft) at the terminal shaft for positive, reliable actuation of fuel racks or steam valves
  • Internal oil pressure: about 1034 kPa (150 psi) operating pressure, higher than UG-5.7/UG-8 to support the increased work capacity
  • Self-contained oil sump: around 1.9 L capacity with relief-valve/accumulator system for stable hydraulic performance and simplified installation
  • Isochronous or droop control: dashpot and needle-valve compensation enable very stable speed control, with adjustable droop for accurate load sharing on generator sets
  • Drive & speed range: designed for governor drive speeds in the 375–1500 rpm range, with a recommended constant-speed operating band from 1000 to 1500 rpm; suitable for clockwise or counter-clockwise drive rotation

These features make the Woodward UG-10 governor a widely used solution for reliable, long-term engine speed control in heavy-duty environments.
