K(B)SDG4V-3

K(B)SDG4V-3 1* Series Servo-Performance Proportional Directional Valves with Feedback

eaton kbsdg4v-3

The KBSDG4V-3 line offers a range of proportional directional valves with integral control electronics. Factory-set adjustments of gain and offset ensure consistent reproducibility valve-to-valve.

These four-way solenoid operated proportional valves have a high dynamic performance which enables them to be used in closedloop applications, previously possible only with servo valves. Various spool options are available for rated flows up to 40 L/min (10.6 USgpm). Working pressures are to 350 bar (5000 psi). The spool position is monitored by an LVDT which feeds back information to the amplifier, enabling spool position to be accurately maintained.

This valve type can be supplied with or without an integral amplifier built directly onto the valve.

KSDG4V-3 Without the integral amplifier.

Pressures to 350 bar (5075 psi)

Features and benefits

  • Wide range of spool and flow rate options
  • Supported by a broad range of amplifiers and auxiliary function modules
  • Electronic feedback LVDT ensures accurate spool position control
  • Internal current feedback provides optimal control
  • Vibration and shock tested
  • Full CE electromagnetic compatibility.

KBSDG4V-3 With integral control electronics.

Pressures to 350 bar (5075 psi)

Factory-set adjustments of gain and offset ensure consistent repeatability valve-to-valve.

The only electrical inputs required are power supply (24V) and a command signal, either ±10V or 4-20 mA (model code selectable). 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 pin allows the function of the valve to be electrically monitored. Ramp functions, if required, can be generated externally.

Features and benefits

  • Factory-sealed adjustments ensure valve tovalve reproducibility.
  • Installation wiring reduced and simplified.
  • Standard 7-pin connector.
  • Standard 24V DC supply with wide tolerance band.
  • Optional command signal, ±10V or 4-20 mA (model code selectable).
  • Valve with integrated amplifier selected, ordered, delivered and installed as one performance-tested package.
  • Spool position monitor pin to help with troubleshooting.
  • Simple valve removal and replacement for service (plug & play).
  • Vibration and shock tested.
  • Auxiliary DIN rail mounted electronic function modules available.
  • Full CE electromagnetic compatibility. - 2014/30/EU
  • IP67 valve, environmental protection rating.
  • Optional valve enable function.
