Energy
Designed for extreme forces, harsh conditions and durability
Safe & reliable
Important features of components with applications in the energy sector are high redundancy, shifting reliability and a long service life. In energy systems, where extreme forces are seen, contained and controlled, hydraulic valves and brake systems are often among the safety-critical control elements.
Explosion protection is also a particularly important issue in specific areas such as oil and gas production or in mines. Our products in the energy sector have been developed precisely for these conditions and are designed to function reliably and accurately even under harsh conditions.
Application remote-controlled vehicles
Remotely operated vehicles (ROVs) are used for a wide range of underwater operations, from observation to complex deep-sea missions. In challenging environments and depths of up to 6,000 m, reliability is crucial. Thanks to our high-quality products, innovation and first-class service, we have earned a leading reputation in the ROV market. With flexible designs and components, we guarantee customized solutions for your needs.
Wind energy application
Wind turbines are designed to withstand the powerful forces of nature, even during storms. This is achieved by a sophisticated hydraulic self-protection system that turns the rotor blades out of the wind and keeps the Nacelle in a stable position. The valves play a crucial role in the safety and functionality of entire system.
Application Hydraulic Top Drives (HTD)
Wandfluh valves for HTDs are low loss, high flow and high pressure to get more work done with the energy used, reducing operating costs and heat generation, extending the life of the oil and system components. Manifold assemblies integrated into HTDs must be compact, efficient and built to withstand harsh environments from drilling process fluids to high vibration and shock loads.
Application Actuators
Large process valves are often actuated hydraulically, using the high-power density of hydraulics to enable compact and efficient solutions. The requirements for hydraulic valves vary depending on the area of application, ranging from standard valves through to explosion-proof designs and corrosion resistant materials.
Application of steam dampers
Steam and butterfly valves are often used in thermal power plants. While they have traditionally been used in coal, oil and nuclear power plants, the importance of renewable energy sources for steam generation is constantly increasing. The butterfly valves act as safety valves that release excess pressure in the system in a controlled manner. They are electronically monitored by the integrated safety systems.
Hydropower application
Hydropower plants utilize generator turbines that are driven by large volumes of high-pressure water. The control of turbine speed and the monitoring of these significant forces rely on hydraulic systems. To ensure a safe shutdown, particularly in emergency situations, Wandfluh has developed specialized hydraulic valves that are actioned by the water pressure in the turbines.

Control
In larger projects, the operation of hydraulic machines are often controlled by a central supervisory system that continuously adjusts parameters to optimize performance. This system can modify the operation of individual valves through command signals and can also monitor sensor data to maintain close and corrective oversight of the process. Proportional valves are typically used for variable and often fine adjustments to flow or pressure, creating a highly flexible system that can be adapted quickly to changing conditions or needs.
Valves with on-board electronics (OBE) or discrete control electronic units that include open loop amplifiers or closed loop controllers convert command signals directly into coil drive signals, ensuring a quick response and precise coordination between the electronic, hydraulic, and mechanical systems for smooth operation.
