KBD/TG4V-5, 1* Series Series Proportional Valves without Feedback
Vickers KB*G4V-5 proportional valves are designed to provide controlled oil flow in proportion to an electrical command signal. They are available in two versions. Firstly a double solenoid version that will provide reversible flow and return to an actuator. Secondly a single solenoid version that provides a single direction of flow.
The KB valve incorporates an integral control amplifier. Factory set adjustments for gain, spool deadband compensation and dither ensure excellent reproducibility valve-to-valve.
Electrical connection is via a standard 7-pin plug and requires a power supply and command signal which can be either voltage or current (model code option).
In addition to improving machine performance and life, the KB proportional valves substantially simplify system design by combining direction and flow capabilities in one single package that mounts onto a standard ISO 4401 interface.
