KBHDG5V7 Proportional Two-Stage Directional Valves Servo Performance with Double Spool Feedback

KBHDG5V7 proportional directional valves come 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. 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. Ramp functions, if required, can be generated externally.
