Proportional directional control valve
with integrated spool position control
Direct controlled proportional directional control valve with integrated amplifier electronics and spool position control in flange construction NG6. The valve is designed for operating pressures of 350 bar and for a maximum volume flow of 40 l/min. Four different volume flow levels are available.
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. With this, the hysteresis can be minimised and the dynamic characteristics massively improved in comparison with conventional proportional directional valves.
Thanks to the integrated amplifier electronics, the compact construction and the good protection against environmental influences, the valve is highly suitable both for applications in industry as well as in mobile hydraulics.
The parameterisation takes place through a RS 232-interface by means of a menu-controlled parameterisation - 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.
