TG-13 is a mechanical-hydraulic governor designed to control API611 steam turbines. It is ideal for pumps, compressors, or generators where constant-speed operation is not necessary.

Functionality

• Speed Sensing: The governor senses turbine rotor speed through an input drive shaft.
• Comparison: It compares the sensed speed to an internal set point.
• Control: The governor adjusts turbine inlet steam flow via a rotary output terminal shaft connected to the governor valve.

Key Features

• Self-contained: Includes an integrated ball head assembly for speed sensing and an oil pump for output force.
• Low Cost: Provides a cost-effective solution for speed control.
• Speed Droop Control: Allows varying turbine speed based on load.
• Counterclockwise Drive Shaft: Compatible with turbine drive shaft rotation.
• Weatherproof Construction: Suitable for outdoor environments.
• Self-contained Sump: Offers lubrication and hydraulic fluid storage.
• NEMA “A” Speed Control: Meets industry standards.
• 16 N m (12 ft-lb) Outputs: Delivers sufficient torque for governor valve control.
• Harsh Environment Compatibility: Designed for challenging operating conditions.
• Certified for HAZLOC and ATEX Locations: Meets safety standards for hazardous areas.

Applications

• Pumps
• Compressors/Turboexpanders
• Force and Inlet Draft Fans
• Generators
