Important Notes

When the oil flow on the primary side is excessive, the sequential operation may not function properly. Please install a flow control valve with directional control at the inlet port of the primary side, or regulate the flow at the hydraulic pressure source.

HSV
3	Pressure Adjustment Range	3: 1.0–6.0 MPa 6: 5.0–18.0 MPa
A	Oil Passage Plate Type
5.0 MPa	Set Pressure (Sequential Operation Pressure Setting)	The difference between the operating pressure and the set pressure must be greater than 1 MPa. When multiple sequence valves are used in parallel circuits, the pressure settings must differ by more than 1 MPa to ensure proper sequencing.
