digital proportional servo valves
3/3-way directly operated servo valves for the flow (LRWD2),
pressure (LRPD2) and position (LRXD2) control
Series LR digital proportional servo
valves are direct driven 3/3-way valves
with a patented rotating spool system
with closed loop control circuit. The
electronic board is integrated into the
valve’s body ready to connect.
Series LR*D2 digital proportional servo
valve has been designed to be as
compact as possible in order to save
space and to be mounted on a DIN-rail.
Thanks to this new digital version, the
valve can be configurated through a
USB connection according to different
requirements.
