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
