Product Description
Product Overview
The Woodward TG-13 8516-038 is a mechanical-hydraulic speed droop governor designed to control API 611 steam turbines driving pumps, compressors, or generators in applications where isochronous (constant-speed) operation is not required. This self-contained unit senses turbine rotor speed via an input drive shaft, compares it to an internal setpoint, and adjusts steam flow through a rotary output terminal shaft connected to the turbine’s governor valve. It is constructed from die-cast aluminum and is widely used in industries such as oil & gas, power generation, and industrial processing.
