Hydraulic Actuators

Proportional actuator with output range of 8, 12, 15, 25, 34 or 40
ft. lbf., used on numerous engine types and applications thanks to its wide range of work output.

Medium and high-speed
diesel engines,
Steam turbines

Gensets
Rail traction

Proportional actuator with output range of 8, 12, 15, 25, 34 or 40
ft. lbf., featuring a mechanical-hydraulic governor as a ballhead backup in the case of a power failure or controller fault, providing various manual speed setting options. Popular actuator model for marine propulsion engines and other applications where common mode failures must be minimised.

Diesel engines

Marine
Gensets

Proportional actuator with output range of 60 or 80 ft. lbf., 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.

Medium-
speed diesel engines

Gensets
Marine

Proportional actuator with output range of 120, 200 or 250 ft. lbf., featuring a two-stage, high stiffness, backlash-free hydraulic servo mechanism for best possible control on large medium-speed engines.
Option for start/boost pressure fuel limiter and/or a mechanical hydraulic governor as a ballhead backup.

Medium-
speed diesel engines

Gensets
Marine

Compact proportional actuator with output of 30 ft. lbf. for use in both new and retrofit applications due to its standard UG-8 compatible base.
Option for start/boost pressure fuel limiter.

High-speed diesel engines

Gensets
Industrial plants

Small proportional actuator with output of 4.7 ft. lbf., using engine oil for its operation but with a self-contained oil pump and accumulator. Can be used with a range of proprietary ECUs, making it an ideal solution for upgrade/retrofit installations.
