  3. Choose Inlet Section
  4. Choose Work Sections
    • Application Spool Selection
    • Spool Position Control
    • Spool Actuators
  5. Choose Outlet Section

Valve Options To Choose From

  • Either open center or closed center hydraulic circuit.
  • Override adjustment option available.
  • Load checks for all work ports.
  • Work port anti-cavitation checks.
  • Work port relief valves.
  • Work port restrictors.

Inlet Section

  • Size of ports
  • Type of ports – pipe thread, oring boss straight threat, 4 bolt flange – this will be for all sections
  • Inlet relief, or inlet relief plug (no relief)

Work Sections

Application Spool Selection

  • Cylinder type spool – a and b work ports are blocked in the neutral position.
  • Motor type spool – a and b work ports are open to the tank passage in the neutral position.
  • Single acting cylinder spool – a port is blocked in neutral and there is no b port.

Spool Position Control

  • 3 position spring return to neutral position.
  • Detent in 3 positions.
  • Rotary friction detent variable from A position through B position.

Spool Actuators

  • Manual lever metering.
  • Rotary lever metering.
  • Hydraulic pressure actuation.
    • -On or -off
    • Proportional pressure metering.
    • Solenoid controlled/pressure actuated.
    • Air pressure actuation
      • -On or -off
      • Proportional pressure metering.
      • Solenoid controlled/pressure actuated.

Outlet section

  • Standard – oil flow directed to the tank when spools are in the neutral and the A or B position.
  • Power beyond – oil flow is directed to power beyond port when all spools are in the neutral position and return oil flow is directed to the tank port when the spools are in the A or B position.
