RE 2800-1G
The 2221 is a proportional actuator where the position of the output shaft is proportional to the electrical input signal 0-1 A. This actuator is typically used in medium/high-speed diesel engines in generator systems, steam turbines or locomotives.
Technical data
More information
Proportional actuator featuring a two-stage, high stiffness, backlash-free hydraulic servo mechanism for best possible control on larger engines requiring increased work outputs. Option for start/boost pressure fuel limiter and/or a mechanical-hydraulic governor as a ballhead backup.

The HPC (Hydraulic Pressure Converter) is an electrohydraulic pressure-regulating control valve designed for use in positioning single-acting steam turbine valve servos. The HPC has been specially designed with extra attention to accuracy, response, resolution and is ideal for both inlet. “Proportional” current (4 ... 20 mA) to hydraulic pressure converter (e.g. 100 ... 500 kPa) for turbine applications that require precise hydraulic pressure control for servo valve positioning. Applications are steam turbine generators like back pressure turbines and condensing turbines. The reliable robust design of the HPC with its IP66 corrosion-resistant housing, super strong rotary actuator driving our linear pilot valve makes it ideal for the most challenging of applications where dirty or contaminated oil may be present.
