Explore modular hydraulic directional controls by valve size, actuation and spool configuration. These records help compare how a valve directs flow within a hydraulic circuit.
Directional valve catalogue
Browse all directional valves for solenoid-operated valves, manual lever valves and solenoid valves with a manual lever. The current documented families include NG-6, NG-10 and NG-16 sizes; available actuation types vary by family.
How to select
Choose the circuit function and inspect the hydraulic symbol before selecting a spool code. Compare valve size, maximum flow and pressure, then the actuation method. For an electrical model, check the stated coil voltage and AC or DC supply. For a manual model, check the lever and return or detent configuration in its catalogue.
Use the exact model reference and source drawing to verify mounting and connections. Spool codes are catalogue identifiers and should be interpreted with their accompanying hydraulic symbols.
