Throttle Bodies

Within a speed control system, a throttle body is used to regulate the supply of the gas/air mixture and thus the speed and power of a gas engine.

MOTORTECH throttle bodies are equipped with a lever for connecting an external actuator. An end stop and a screw for idle speed adjustment provide additional adjustment options for optimum operation of stationary gas engines.

  • For use on naturally aspirated and turbocharged gas engines
  • Use with various types of gas (natural gas, biogas, sewage gas, mine gas, etc.)
  • The series 50, 100, 140 and 200 cover a wide range of applications
  • Butterfly diameter from 1.65 to 4.92 inch (42 to 125 mm)
