Product Description
The QKL-B1T / B2T series is a complete closed loop ser vo system consisting of valves,
manifold, housing and electronic controls. 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-B1T/B2T
and provides a feedback signal to the electronic controls. By controlling these two valves
to maintain precise pressure.
