Proportional Directional Valves, LVS18

Description

This range of proportional valves is used to provide load-independent speed control of motors and cylinders. The LVS18 is operating according to the flow sharing principle. Also available with rapid-traverse and floading function.

Advantages

  • Safe volumetric flow control by flow sharing principle, prevents the functional hold-up caused by undersupply.
  • Load-independent flow control, even with parallel operation of several acuators
  • Load feedback
  • Actuator sections with individual pressure compensators
  • Secondary pressure relief valves
  • LS pressure relief for the whole control block
  • With rapid-traverse and floating position
  • Energy saving by low pressure drop
