Product Overview
The Vickers KBS2-03-39-NS-11-E-CO-A-NS-VSC-NS-004-11 is a high-performance proportional directional valve engineered by Vickers (Eaton) for precise electro-hydraulic control of flow direction and magnitude in demanding industrial hydraulic systems. Utilizing a robust spool-and-sleeve design with proportional solenoid actuation, this valve delivers infinitely variable flow control proportional to the electrical input signal, enabling smooth acceleration, deceleration, and positioning of hydraulic actuators. The KBS2 series is widely recognized for its exceptional response characteristics, low hysteresis, and high repeatability, making it an ideal choice for closed-loop and open-loop control applications where precise motion control is critical.
