Load-sensing proportional directional

valve offers enhanced flexibility

aton today announced the launch of its
SLV20 load-sensing proportional
directional valve, a flexible priority-
Eflow-sharing solution for mini and
micro machinery. Compared to traditional cast
iron control valves, Eaton’s SLV20 valve
offers greater flexibility and control as well as
space and weight savings for low-flow
applications.
Eaton’s SLV20 valve brings priority flow
sharing to low-flow machinery with the
versatility and serviceability of screw-in
cartridge valves. Designed in sections to
enable stacking of multiple functions, the
SLV20 valve utilises Eaton’s new ESV9 four-
way three-position proportional solenoid
cartridge valve in a hydraulic integrated circuit meter-out compensator reduces section size by
concept. Meter-out or meter-in control is 40%, saving space on the machine.
