Category: 4WREE

WRE(E) direct operated proportional directional control with integral feedback are available with or without on-board electronics (OBE). Positive overlap spools reduce leakage at center, while underlap spools can be utilized for closed-loop functions. Individual amplifiers are available, while OBE models are possible with either a voltage or current command.
