Product Description
Woodward 8516-050 TG-13 Turbine Governor
Product Overview
- The Woodward 8516-050 is a TG-13 Turbine Governor, designed for precise speed control of small mechanical-drive steam turbines or turboexpanders in industrial applications such as power generation, oil and gas, and process industries. This mechanical-hydraulic governor is part of Woodward’s TG (Turbine Governor) series, providing reliable and responsive speed regulation for turbines driving pumps, compressors, or generators. The TG-13 model is a self-contained, lever-operated unit that uses hydraulic amplification to control turbine speed by adjusting the steam valve position, ensuring stable operation under varying load conditions. The 8516-050 is a specific variant of the TG-13, potentially featuring specific configurations, such as a particular speed range, output torque, or mounting options, compared to other TG-13 models. It is designed for rugged environments and offers simple, maintenance-friendly operation without requiring external power sources. The 8516-050 is distinct from Woodward’s electronic control systems, such as the EasyGen series (e.g., 8440-2179 EasyGen-3500XT, 8440-2050 EasyGen-3200-5), EGCP-3 series (e.g., 8444-1082), SPM-D2 series (e.g., 8446-1048), 2301D/E series (e.g., 8273-1011), 505D series (e.g., 8200-1300), Peak150 series (e.g., 8200-176), ProAct series (e.g., 8237-2595), 723PLUS series (e.g., 8270-1013), EPG systems (e.g., 8290-195), electronic governors (e.g., 8406-121), and actuators (e.g., 8408-921), focusing on mechanical-hydraulic speed control for small steam turbines.
