FCC3W series line type pressure sensitive 3-way flow control valves adjust the speed of the fluid entering port E through the flow control valve and allow it to be sent to port P by discharging the pressure and flow rates formed in the system from port S tanks to the hydrostatic balance piston located in it and stabilizing the pressure and flow of the fluid ın port P. It allows the hydraulics to pass the speed adjustment easily on the return at the P port.
