Single-acting load control valve (overcenter) - modular type - CETOP 3. Seal by conical plunger. Suitable for open centre hydraulic circuits, i.e. A and B lines on unloading.
OPERATING
Valve setting (Pt) has to be 1,3 times higher than load pressure (Pc).
Valve influenced by the counterpressure at unloading (PV). By setting, it will appaer a light oil drain external to the valve through the adjusting screw.
This allows to eliminate the air inside the circuit.
