High Response Directional Valves

High Response Directional Valves FOSA

Bucher Hydraulics introduces the groundbreaking FOSA high-response valve series, setting a new standard in fluid power technology. This innovative solution represents a technological leap forward by seamlessly merging the reliability of proportional valves with the precision of servo technology in a single, uncompromising package. Where traditional proportional valves trade dynamic response for durability, and servo valves sacrifice robustness for speed, FOSA valves deliver the perfect synthesis – exceptional performance without compromise. Engineered with cutting-edge technology, FOSA valves achieve what was previously impossible: up to 60% reduction in energy consumption while maintaining industry-leading durability and an unmatched price-to-performance ratio. The secret lies in their advanced stepper motor actuation and optimized control spool geometry, enabling instantaneous response times below 1ms with virtually load-independent operation. These technological advancements translate directly into operational benefits – reduced system complexity, lower total cost of ownership, and extended service intervals even in the most demanding environments. From high-speed metal forming presses requiring micron-level accuracy to mobile hydraulic systems operating in extreme conditions, FOSA valves elevate performance across diverse applications. Their compact NS6 footprint outperforms conventional NG10 valves while occupying 30% less space, offering system designers unprecedented flexibility. The zinc-nickel coated components and ISO 4401 compliant design ensure reliable operation in corrosive environments and simplify integration into existing hydraulic systems. More than just a component upgrade, the FOSA series represents a paradigm shift in hydraulic system design. By eliminating the traditional trade-offs between speed, precision and durability, Bucher Hydraulics empowers engineers to create more efficient, responsive and reliable hydraulic systems. Whether optimizing existing machinery or designing next-generation equipment, FOSA valves provide the technological edge to outperform competitors while reducing energy costs and maintenance requirements. For system integrators and OEMs seeking to future-proof their hydraulic solutions, the FOSA series delivers measurable advantages where it matters most – in energy efficiency, operational reliability, and total cost of ownership. This is hydraulic engineering evolved, combining Swiss precision with industrial toughness to meet tomorrow’s challenges today.
