Two-and three-way proportional cartridge valves mount in electrohydraulic manifold blocks to provide flow and pressure controls according to electronic reference signals. They are available in sizes 16 to 80 and withstand vibration and mechanical shocks. Digital control offers low hysteresis, fast response time, high linearity, and stability. Numerical software is easy to set. They interface directly to field-bus networks.
