The 4/3 LS directional valve is progressive or proportional. The control can be manual, electric or hydraulic.
It is used in mobile applications (public works, agriculture, ports, etc.). It makes it possible to manage the speed of the receivers and to facilitate the operation of the machines. Simultaneous movements are possible. Depending on the options chosen (individual pressure balances for example), handling the machines is greatly facilitated.
The LS directional valve can be connected to a fixed or variable displacement pump.

This circuit need " pressure compensation valve " for operating 2 actuators same time.
Pressure balancing valve(Ls differential valve) not enough...

[@sebhydroformation2732]

Yes we need pressure compensation valve on each directional valve
