Rotary Actuators with Gearing
The range of electrically driven actuators with gearing is based on a DC disc motor, which has been combined with a gear mechanism. These actuators provide a nominal torque of 4 Nm to 180 Nm and a control angle of 36° or 42°. They are used in medium-sized and large diesel and gas engines, as well as gas and steam turbines. The actuators can be combined with various analogue or digital HEINZMANN governors and provide contactless position feedback.
These actuators are mainly used in industrial engines. They are driven by analogue or digital HEINZMANN governors or by the JANUS positioning module.

Direct Acting Rotary Actuators
This is a range of direct-acting actuators with a rotating shaft and an all-electric drive concept. The torque varies from 0.55 to 13 Nm at a maximum control angle of 36°, 53°, 68° or 70°. They are primarily used for diesel and gas engines with outputs from 100 to 1,000 kW in vehicles and in industry, and can be combined with various analogue and digital HEINZMANN governors.
These actuators are available as spare parts and used in industrial engines producing less than 180 kW. They are driven by analogue governors. Follow-up products are actuators of the 2000 series.
Technical data
Diesel Engine Gas EnginesThese powerful and robust actuators are mainly used in small and medium-sized diesel and gas engines or turbines. They differ in their maximum torque and their operating temperature range. The actuators can be used in the harshest ambient conditions and at ambient temperatures of up to 150 °C.

Gas Turbines
Steam TurbinesThe DP versions of our actuators have been designed for direct installation on conventional diesel injection pumps, and are driven by HEINZMANN digital governors. They are mainly used in industrial engines producing 100 to 1000 kW. They are primarily used to replace mechanical governors in diesel and dual-fuel engines, allowing them to benefit from the additional functions provided by electronic governors.

Diesel Engine Industrial VehiclesThe StG 2120 is tailored to engine and turbine applications and their specific ambient conditions, and is controlled by HEINZMANN digital governors or HEINZMANN positioning modules. Its higher explosion protection class makes it ideal for use in gas turbines and gas engines that are subject to more stringent requirements.
Technical data
TurbinesThese models are the most powerful versions in the 2000 actuator range, and can be driven by analogue and digital HEINZMANN governors and by positioning modules. They are used in diesel, gas and dual-fuel engines and can be integrated with various throttle valves for hot and cold engine applications. The brushless permanent magnet system makes this actuator series ideal for use with gas engines.

with rotary actuators
This HEINZMANN range is based on the standard versions of our actuators and is equipped with integrated positioning electronics. The nominal torque range is from 4 Nm to 44 Nm at a rotary angle of 68° or 90°. These models are mainly used in medium/large gas engines and dual-fuel engines. These devices can be actuated by any electronic speed governor that supplies an analogue position setpoint signal.
These two positioners can be used in internal combustion engines of all types with low and medium power. The versions differ in their maximum torque and working temperature range. The devices can be mounted in any installation position. The rugged and resistant design and the protection class IP6K9K allow the use even under harshest environmental conditions.

These positioners stand out by offering high performance and a fast response. The disc-type motor generates a high level of torque, which is multiplied by a planetary gear. Should the power supply fail, an independent locking mechanism prevents any adverse reactions by the linkage. What’s more, the IP66 degree of protection ensures the model provides optimum resistance in harsh environments.
