Sequence valves are used in power workholding circuits for pressure dependent sequence control. The compact size allows mounting directly to the clamping fixture, requiring only one pressure line from the power unit to the fixture for single-acting cylinders.

Application example
Application example 1

The workpiece is to be positioned and clamped in the fixture with hydraulic clamping cylinders.

Clamping sequence

  • Cylinder 1 pushes workpiece against stop a.
  • Pressure rises to 30 bar, sequence valve opens.
  • Cylinder 2 and 3 extend and push the workpiece against stop b and c.
  • Oil pressure rises uniformly in all cylinders, because of the throttle-free passage of the opened sequence valve.
Application example 2

Sequence control for 5 single-acting clamping cylinders.
