We have 10 years experience in assisting in the modernisation of steam turbines, pilot valves and main steam valve controls. Olsen have supplied the Exlar GSX series actuators with Unidrive SP to the Compressor Controls Corporation and Emerson Process Management for significant modernisation projects.

Since the stabilisation of grid frequencies in Eastern Europe, our actuator solutions have proved particularly popular throughout this region. With many turbines over 10 years old, the hydraulic systems and controls often require extensive maintenance and present users with associated fire and downtime risks/costs.

We are focused on the development and implementation of specialised drive solutions based on electric cylinders with associated servo control systems and positioning & monitoring software, including packaged solutions combined with supply of high temperature low smoke cables, turbine speed sensors and linear displacement position sensors LVDT.

With over 1000 actuators supplied and in service in a wide range of steam turbine valve control applications, you can be confident in the reliability and performance improvements compared with legacy hydraulic systems.

We understand the complex and often unique solutions required in power generation. You can work closely with us or leave us with a complex problem to solve on your behalf, it is completely down to you how to utilise our expertise here at Olsen. We are happy to fit in with your way of working.

Designed and tailored in the UK but shipped globally, our actuator solutions can incorporate integrated drive electronics, require no pipes or cooling and are incredible lightweight and compact in comparison with hydraulic systems.

Our actuator solutions are able to meet specifications including:

• Milspec COTS, EAR99 750g, -40°C to +70°C
• Pressure compensation (for subsea)
• Linear Rotary 2000 kNm
• 650 bar operating pressures
• 1 kN to 1500 kN
• ATEX rated
• Travel up to 2 metres
• AC or DC voltage source
• Cables
• Servo drive electronics and software integration
• Multi-axis control synchronisation

The longevity and low maintenance offered through our unique roller screw technology is particularly popular where product failure or downtime can be critical and very costly. A simple-to-use Windows-based interface means the actuators are quick to install, commission and simple to maintain.

The efficiency benefits are also significant. Without the need for messy, leaky and corrosive hydraulic fluids, and with huge operational energy, weight and space savings available, our actuators and solutions are proving even more at home in an increasingly efficiency-driven world.

Olsen Actuation are leading the way in pushing forward roller screw electro-mechanical control systems. We are always happy to explore new applications, requirements and restrictions to find and develop new solutions to help drive the industry forward. If you have any questions regarding an existing project or one in the pipeline, we would be happy to help you.
