Proportional control valve with integrated DSV electronics
The proven proportional spool valve with integrated spool position control now has the option of a 7-pole connector that corresponds to the connection standard used in many places. Thus the position signal of the valve spool is available as an analogue feedback value. The valve controls the volume flow proportionally to the preset command value from 0 to 30 l/min finely and precisely. This up to a pressure of 350 bar. The valve is perfectly suitable for demanding tasks, due to high resolution, high volume flow and low hysteresis and very good dynamic properties. The valve is used where highest precision, high valve-to-valve reproducibility, simple installation and comfortable operation are very important. The integrated controller can operate axes (position, angle, pressure etc.) in a closed control system and thus relieves the machine controller. The integrated electronics offer various options, from an analogue to a digital fieldbus interface (CANopen, Profibus DP). The applications are in the industrial and mobile hydraulics for smooth and precise control of hydraulic actuators. The valve of the nominal size NG6 is available as a 4/3-way function with the designation WDRFA06. The valve is factory set and adjusted, so that an exchange in the machine becomes a simple Plug and Play.
