Eaton offers proportional directional valve

Power management company Eaton’s new SLV20 load-sensing proportional directional valve is designed for priority flow sharing for mini and micro machinery.

The SLV20 valve is designed in sections to enable stacking of multiple functions and uses Eaton’s new ESV9 four-way three-position proportional solenoid cartridge valve in a hydraulic integrated circuit concept. Meter-out or meter-in control is achieved through logic elements, which enables flow sharing and flow prioritisation in the same valve bank.

The valve's sections are manufactured from aluminium drawn bar, enabling production of small batches of individual sections with added functions. This could include pilot-operated check valves, counterbalance valves or other bespoke functions, reducing the need for remotely mounted ancillary valves.

The aluminium sections weigh significantly less than traditional cast iron sections. A patent-pending multifunction meter-out compensator reduces section size by 40%, saving space on the machine. It has flows of up to 60 l/min (16 gal/min) at the inlet and 30 l/min (8 gal/min) at the work port.
