Proven technology that can meet even the most extreme requirements
Whenever it is a question of applying high actuating forces combined with fast or short actuating times with high levels of control quality, even under extreme conditions, electro-hydraulic actuator systems by REINEKE are the best choice. The hydraulic units, referred to as actuator systems, are oil supply units and hydraulic cylinders connected by means of a piping system, and are used to actuate valves or groups of valves.
Even large actuating forces (up to 3,000,000 N) and actuating torques (up to 700,000 Nm) can be precisely controlled. You have the choice between continuous control, step control and open-closed function. At the same time, it is possible to actuate multiple, independent actuators using one common hydraulic system. A redundant version with automatic switching is also possible if required.
When are electrohydraulic actuation systems the right choice?
Electrohydraulic actuation systems are used wherever high actuating forces, short operating times, and precise control must be combined reliably. They are particularly suitable for valves, dampers, and other actuating devices that need to operate safely, powerfully, and accurately under demanding operating conditions.
Typical applications include power plants, waste-to-energy facilities, desalination plants, process steam systems, biomass plants, heavy industry, environmental engineering, and other industrial applications with high requirements for availability, operational reliability, and control accuracy.
High forces and precise control
Electrohydraulic actuation systems offer significant advantages when electric or pneumatic actuators reach their limits – for example, where high actuating forces, high torque, fast operating movements, or dynamic control processes are required.
REINEKE's electrohydraulic actuation systems are individually engineered to meet the specific requirements of each application and provide high actuating forces and torque. At the same time, they enable precise control of valves and dampers – whether for continuous control tasks, step-by-step positioning, or simple open/close applications.
Reliable even under demanding conditions
Thanks to their robust design, REINEKE electrohydraulic actuation systems are ideal for applications where reliability and availability are essential. They have proven themselves in industrial processes involving high loads, challenging environmental conditions, or increased demands on operational safety.

Versatile applications and proven performance
Electrohydraulic actuation systems are frequently used to control the movement of mechanical components such as valves, dampers, actuators, or turbines. They enable precise positioning and control of movement.
At the same time, the systems are capable of regulating the pressure or force applied to a specific component or application. This is required in many industrial processes to maintain the desired operating conditions. Electrohydraulic actuation systems can also control the flow of liquids or gases within a system. This is essential in many applications, such as industrial fluid supply systems.
In applications requiring torque, the systems are used to precisely control and monitor the required torque. REINEKE provides customized solutions precisely tailored to your specific requirements. From project planning and design to delivery and installation – with us, you receive everything from a single source.

Our hydraulic actuation systems are precisely adapted to your requirements. During planning, design, and manufacturing, you benefit from our 40 years of experience and more than 2,400 delivered units. REINEKE electrohydraulic actuation systems are used worldwide.
High-quality materials, precise manufacturing and robust technology guarantee safety
Safety always has top priority for REINEKE engineers. Should there be an energy failure in the electro-hydraulic actuator systems, we offer a variety of fallback scenarios:
- Blocking at the last control position
- Moving to the end position by means of a hydraulic accumulator or through spring force
- Sufficient dimensioning of the accumulator for "emergency strokes"
- Design for indoor or outdoor installation, offshore plants or extreme temperatures
- Redundant programmable logic controllers from reputable manufacturers (e.g. Siemens, General Electric (GE) or Allen Bradley), in order to improve the availability of your application.
- Approval for pressure vessels in accordance with national standards, e.g. DOSH, DPEM, ASME, pressure equipment directive (PED)
We are also happy to take on special challenges – for example, if you require a hydraulic actuating system in potentially explosive areas of the plant or an application in accordance with IEC61511 (SIL). We would be happy to develop a tailor-made solution for you. Simply contact us here for a first meeting.
Actuator systems by REINEKE – pioneering technology coupled with knowledge from 80 years
The internal control of our actuator systems, and monitoring with signal exchange using control station technology, is effected with the help of a programmable logic controller (PLC) and a graphic touch display on site. On request, we can offer you the option of a plain text display for all operating conditions, signals and fault messages. Integration into a single or redundant bus system is also possible. We can offer you tailor-made solutions that also meet the requirements of the future.
