The directional control valve sends the flow to the machine's functions. It is chosen first on the flow rate it has to pass and the pressure of the circuit, then on the number of sections, the spool configuration and the type of actuation.

The spool centre in neutral is the point most often overlooked: an open centre returns the flow to tank and suits a fixed-displacement pump, whereas a closed centre is essential in front of a variable-displacement pump. Getting this wrong makes the system run hot, or holds it under pressure permanently.

  • The monoblock valve is simple and leak-free but fixed: the number of sections and their functions are settled when you order.
  • The sectional valve stacks section by section and can be extended later, at the cost of seals between sections and tie rods torqued to spec.
  • Solenoid valves mount on ISO 4401 standard subplates, size 03 (NG6) or 05 (NG10), with 12 or 24 V DC coils.

We help you read an existing circuit diagram and identify a valve you have removed, and we supply the relief valves, check valves, coils and controls that go with it.
