Freewheeling Valve PTV-FW1

The PTV-FW1 Freewheeling Valve is intended for use in the drive train of a mobile machine with a closed circuit. The valve is used to control the mode of a drive axle in either freewheel mode or drive mode (e.g. Poclain wheel hub motors).

The valve is used to connect the machine's hydraulic drive motors from a freewheeling position to the drive (pump). Unswitched, the axle is not driven, so it is in towing mode. The connection to the pump is established. Since the pilot pressure is routed via the control spool, this results in a smooth shift.
