flow match valve

[siavash1111]

Rexa electro hydraulic actuator uses two FMV (flow match valve ) in their actuator circuit . I am not familiar with this type of valve ,Anyone know is there an alternative valve in fluid power products range ?
Theory of operation of the unit can be found in below link :

The operation of the FMV sounds like a pilot-operated check valve. When pressure is applied to one side of the cylinder, that pressure opens the check valve on the opposite side to allow flow out of the opposite side as flow enters the first side. Direction of cylinder operation is determined by the pump rotation direction instead of a directional control valve and a single rotation direction pump. The directional control valve is eliminated in this method of cylinder operation and control.
