Product Description
The QKL-B1S / B2S series is a complete closed loop ser vo system consisting of valves, manifold, housing and electronic controls, and can be used for 34bar high pressure propor tional control. The output pressure is propor tional to the input electronic command signal. The pressure is controlled by two solenoid valves, one valve functions as inlet control, the other as exhaust.
The pressure output is measured by an internal pressure transducer to the QKL-B1S/B2S and provides a feedback signal to the electronic controls. By controlling these two valves to maintain precise pressure.
