Valves for the most demanding applications—engineered for maximum precision and reliable performance, even under extreme conditions. Certified pressure relief ensures safety and consistent, trouble-free operation.
Renewable Energy
In the field of renewable energy, power plants must ensure stable and efficient energy generation under variable environmental conditions. Wind turbines, in particular, are exposed to highly variable wind conditions and high mechanical stresses.
For the development of components such as pitch control systems, hydraulic systems, and filter systems, this means specifically refining existing solutions and adapting them to real-world operating conditions. A thorough understanding of operational processes, combined with close collaboration with manufacturers and operators, leads to lasting success.

ARGO-HYTOS hydraulic systems for safety-critical applications must meet the highest standards of reliability, availability, and ease of maintenance. High-performance valves play a central role in this, ensuring reproducible and reliable switching cycles. Thanks to their high precision and long service life, they ensure stable operation in demanding applications such as pitch control, rotor holding brakes, azimuth brakes, and rotor lock safety devices. This valve technology is complemented by high-performance filtration systems that make a decisive contribution to protecting sensitive components. High-quality pressure, return, and bypass filters ensure the continuous removal of particles and contaminants, thereby guaranteeing the reliable operation of proportional and servo systems. In large gearboxes in particular, efficient lubricating oil filtration is essential to minimize wear while enabling long service intervals.
Continuous oil condition monitoring enables the early detection of oil aging, contamination, and mechanical wear. The combination of high-precision valve technology, efficient filtration, and intelligent condition monitoring creates a comprehensive system that enables maximum plant availability and extended maintenance intervals.
