Proportional directional valves, SC22

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
