NG4-Mini Proportional Valve

Proportional directional control valve
with integrated spool position control 
NG4-Mini from Wandfluh AG

Direct controlled proportional directional control valve with integrated amplifier electronics and spool position control in flange construction NG4-Mini. The valve possesses an integrated position control. With the spool position sensor (LVDT), the actual position of the valve spool is continuously recorded and brought into line with the set-point value transmitted in an analogue manner. Apart from an analogue interface the valve is also available with a field bus interface (CANopen or Profibus DP). The parameterisation takes place through a USB- interface by means of a menu-controlled parametrisation- and diagnostics software. The data are stored in a non-volatile memory. Settings once elaborated can be reproduced and transferred without any problem, also following an electric power failure.
