Proportional Directional Valves, SC18 / SC22

 

 

Description

This range of proportional valves is used to provide load-independent speed control of motors and cylinders.

Advantages

  •    -  Compact sectional design
  •    -  Adaptable building-block system
  •    -  Low weight
  •    -  Individual matching of flow rates
  •    -  Up to 8 actuator sections
  •    -  Parallel operation (individual compensators)
  •    -  Primary pressure relief for each actuator
