Optimal control technology for any type of gas engine

HEINZMANN provides a wide range of actuators that cover practically all applications and can easily be installed on any gas engine. This means our devices are also ideal for retrofitting on existing systems. Our actuators are lightweight and compact, and offer not only a high degree of protection but also high nominal torques. We also supply integrated solutions, including actuators with integrated positioning electronics or actuators combined with throttle valves.

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.
