KBFDG5V8 Proportional Two-stage Directional Valves High Performance with Main Stage Spool Feedback

KBFDG5V-8 Vickers proportional valves are suitable for working pressures up to 350 bar (5000 psi) and flow rates to 375 l/min (99 USgpm). They are designed to provide a controlled oil flow in proportion to a command signal, with spool position feedback to provide accurate control.

A range of proportional directional valves with control amplifiers built directly on, and prewired to the valves. Factory-set adjustments of gain, spool deadband compensation, and offset ensure high valve-to-valve reproducibility.

The only electrical inputs required are power supply (24V) and a voltage command signal of ±10V or 4-20 mA. The amplifier is housed in a robust metal enclosure, sealed against ingress of water and other fluids. Electrical connections are via a standard 7-pin plug.

A spool position monitor point allows the function of the valve to be electrically monitored.
