ITB Throttle Bodies with Integrated Stepper Motor

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 ITB throttle bodies are equipped with an integrated stepper motor, which eliminates the use for an external actuator. The stepper motor is extremely precisely actuated by the VariStep3 stepper motor driver in combination with the SC100 speed controller.

  • 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)
  • Use of high-temperature ball bearings, designed for low-friction operation
  • Additional sealing of the throttle body shaft for installation before and after the turbocharger
  • O-rings embedded in the housing are used for flange sealing instead of paper seals
  • Butterfly and shaft made of stainless steel
  • Rigid design for long service life
  • Other sizes and custom made designs on request
  • High-resolution stepper motors
  • Precise adjustment due to microstep operation
  • Short adjustment times for butterfly position
  • Very precise control of the programmed positions without overshooting
  • Mounting position of the throttle body is freely selectable
  • Applicable for temperatures up to 257 °F (125 °C), High temperature types (-HT) up to 392 °F (200 °C)
  • Precisely actuated by the VariStep3 stepper motor driver and SC100 speed controller
