The electromagnetic proportional directional control valve adopted in flexible intelligent sprayer chassis is PRM2-063Z11.
The time of switching the directional control valve should be added to this value.
In load-sensing valve control systems, sensed pressure is used to adjust the setting of a control signal to adjust the relief valve setting, but it would be possible to apply the technique to flow control, as is done in pressure-compensated directional control valves (Fig.
* All ports are blocked when the directional control valve is in center or neutral position (shown).
As well as the transmissions, ZF's scope of supply also includes the control valve block which consists of a 4/3 directional control valve for the gear shift and a pressure protection valve with an integral pressure reduction function.
5 is a modification of the basic pressure-holding circuit: the weighted accumulator is connected to the cylinder line downstream of the directional control valve. When a control device is in placed, it controls only that particular line.
Sauer-Danfoss has added two mobile hydraulic valves to its directional control valve line in North America.
This design eliminates the need for a directional control valve to sequence flows.
The control system consists of: a GoldCup series P6 - P30 axial piston pump with integral displacement sensor; a high response 4DCO1 proportional directional control valve with integral LVDT; and an ECO1 digital electronic controller in Eurocard format.
