Technologies empowering efficiency 

To ensure that combustion engines operate very efficiently, turbocharging is absolutely essential to improve the power output and the engine’s efficiency. For this reason, sophisticated control elements are required on the side of the hot engine exhaust gases in particular, in order to precisely and reliably control the boost pressure. HEINZMANN can provide this equipment, which includes all components required to control the wastegate.

Wastegate Valves

The wastegate throttle valves are used to control turbocharged engines. The throttle valve determines the amount of exhaust gas driving the turbocharger’s turbine. This is because the load depends on the torque of the compressor wheel, which is connected to the turbine via a shaft. When closed, the throttle valve stops ensure a better seal and minimal leaks. This arrangement means that the blocking cannot occur in the closed position.

Wastegate Valves

  • Resistant to high temperatures and corrosion
  • Optimal sliding properties over a wide temperature range
  • Connection to the actuator can be established using a linkage or a shaft with a high-temperature coupling

Flat housing

  • Operating temperature: -40 ... +550 °C; up to +750 °C on request
  • Max. differential pressure: 5 bar abs.

Housing with flange

Technical data

  • Diameter: 120, 170, 200 mm
  • Operating temperature: -40 ... +550 °C; up to +750 °C on request
  • Max. differential pressure: 5 bar abs.
  • Turbocharger Bypass
  • DK 100 / StG 3
  • DK 100 / StG 3-PD
  • DK 140 / StG 2080-PD

Turbocharger bypass throttle valves have been specifically optimised for this field. They have been specially designed to withstand the higher differential pressures that occur in this application. The turbocharger bypass valves are also available with a return spring that acts in the other direction.
