This hydraulic sequence valve is especially suitable for clamping circuits. The applied pressure determines the sequence of cylinder operation. Compact and resistant to high pressure. Can perform the correct sequence of actions immediately when installed in a hydraulic circuit and dose not require any additional controls.
This product includes Type A manifold model and Type B tubing model options. The appropriate selection may be made in light of overall clamp design requirements.
To insure reliable operation of sequence vaves they should either be located in parallel or in a multilayer arrangement. The minimum pressure difference across each sequence valve should be 25kg/cm².
A:Manifold Type
B:Line Type
Pressure adjustment range 0-350kg/cm²
Clamping seqnence
Cylinder 1 pushes workpiece against stop a.
Pressure rises to 40kg/
cm² and sequence valve opens.
Cylinder 2 and 3 extend and push the workpieces against stops band c.
Because of free passage through thr opened sequence valve, pressure rises uniformly in all cylinders.
