Choose maximum oil flow – GPM = gallons per minute

  • 10 to 20 GPM = V20
  • 20 to 40 GPM = DVA20
  • 40 to 70 GPM = DVA35
  • 70 to 120 GPM = DVG80 or V90

Choose maximum pressure 2500 PSI, 3500 PSI, 5000 PSI

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.
