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 closed loop 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.
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.
