HY-DBVSA-1LG (Inverse-proportional Pressure Reducing Valve)
Series HY-DBVSA-1LG. Inverse-proportional pressure-relief valves consist of a spool-type main stage and a leak-free, poppet-type pilot stage with a falling pressure/current characteristic. Thanks to the damping of the solenoid armature, these pressure-relief cartridges exhibit excellent stability over the whole pressure and flow range. In control mode, the relief pressure is inversely proportional to the change in the required value (amplifier output current).
