Throttle Valves

HEINZMANN throttle valves control the flow rate of the gas-air mixture. Thanks to the wealth of sizes from DK 50 to DK 400 and the dense design, these models can handle a wide range of power outputs and operating pressures. The control angle for the throttle valves is 75°. Both control directions can be used in equal measure.

Throttle Valves with Actuators

HEINZMANN throttle valves with actuators are the ideal components for ensuring optimal engine control, including for turbocharged engines. As throttle valves, they regulate the engine speed by metering the mixture accordingly, and boast an unusually long service life. What’s more, they can be used in special applications as a gas valve in order to control the air-fuel ratio. Alternatively, they can also be used as a turbo bypass valve.
