PVBS main slide for flow control.
Respectively for basic module with or without LS diverter valve. With standard flow control sliders, the pump pressure is determined by the highest working pressure. This happens either via the pressure adjustment slider in the Open center PVP (pumps with fixed displacement) or via the pump's regulation (pumps with variable displacement). The pump pressure will therefore always correspond to the load pressure plus the spring bias of the pressure adaptation slider or pump regulation (stand-by pressure). This usually gives an optimal and stable regulation of the oil flow.
