Electrically Actuated Diesel Throttles

eact4

Also known as pre-throttles, throttle governors, and intake shutter valves, these valves are used to increase manifold vacuum in diesel engines.

Applications:

  • Increasing EGR gas flow-rate for emissions controls
  • Providing low minimum flow to aid NVH in smooth diesel engine shut-down
  • Diesel particulate filter regeneration.

Key Features:

  • Aluminum body to meet stringent vibration and temperature requirements
  • Composite valves available for cost competitiveness
  • DC motor and composite gear-train to meet high torque requirements
  • Corrosion resistant components for low pH application
  • Contactless position sensor for improved reliability
  • Weight: 370 grams
  • Throttle Diameter: 48mm ~55mm
  • Working Temperature: - 40°C ~ 140°C
  • Transition time: Fully closed to fully open in ≤120 m
  • Flow Characteristics (for 50MM)
  • At full open: 338 kg/hr. min ( Δp @ 2kPa)
  • At full closed: 3.7 Kg/hr. max ( Δp @ 80kPa)
