Advancing Intelligent Hydraulics
High-response hydraulics valves offer the greatest performance in proportional directional valve technology. Primarily used in closed loop systems to control position, velocity, pressure, or force – high-response proportional valves are a powerful tool for advancing intelligent hydraulics in your systems. Rexroth has engineered these directional control hydraulics valves to approach a servo value performance on a cost-effective basis, for the same flow range.
