Catalogue Description Mobile Directional Control Valve Catalogue layout This catalogue is designed to give an overview of the F130CF directional valve and to show how it can be customised to meet your needs exactly. Apart from general information and basic technical data therefore, the catalogue contains descriptions of the variety of options available for the different function areas of the valve. After you have studied the options and made your selection, we will tailor your valve to meet your operating and control criteria. Each function area is given as a subheading, followed by a brief...

Valve Description Mobile Directional Control Valve The F130 directional valve is of modular construction. Designed for many different applications, it is used in cranes and other types of construction machine, forestry machines, refuse trucks, drill rigs, fork-lift The F130 is available in three different versions: the F130CF with an open centre for fixed pumps, the F130CP with a closed centre for variable displacement pumps and the F130LS with a closed centre, coupled with a load sensing signal, to the variable displacement pump. Compact system construction The valve is of modular...

System Description Mobile Directional Control Valve Basic circuit diagram, CFO. For information about different hydraulic systems, see our system The F130 is designed with an open centre. The type diagrams on the right show the control characteristics The valve is also suitable for use in systems with variable pumps. q(l/min) Flow rate in service port In the F130CF with hand-operated spools, the speed is influen- ced by the size of the load, i.e. the heavier the lift load, the longer the lever stroke needed before the load starts to move, and the heavier the sink load, the quicker the...

System Description Mobile Directional Control Valve Principle circuit diagram for valve with closed centre. Principle circuit diagram for valve with load sensing (LS). Flow rate in service port Flow rate in work port In the F130CP with hand-operated spools, all loads start moving In the F130LS equipped with PC and ECS closed spool- at the same point, regardless of the size and direction of the actuators, the spools are pressure compensated, with the result load. The size of the load does, however, affect the slope of the that the load's influence on speed is negligible. curve to some...

System Connection Mobile Directional Control Valve A. Series connection, multi-valve system, F130CF only The pump is connected to the first valve. Flow that is not directed to a consumer via the first valve continues to the next valve. The first valve therefore has priority and, in the event of full spool actuation in the first valve, no flow continues to the next valve. If an additional pump is connected to valve 2, then valve 2 receives the flow from pump 2 plus any residual flow from Inlet section End section Inlet section End section Spool section / \ Spool section B. Series connection,...

Environmental Characteristics Mobile Directional Control Valve The valve can be mounted in any direction. However, the mounting base should be flat and stable so that the valve is not subjected to strain. If the valve is mounted with the cap of the spool actuator facing downward, then cap A13 should be chosen The O-rings in the valve are mainly made of nitrile rubber, NBR. The O-rings in the joint face between the sections are made of hydrated nitrile rubber, HNBR, because HNBR tolerates heat Oil temperature, working range Hydraulic fluids Best performance is obtained using mineral-base oil...

Inlet Sections Mobile Directional Control Valve Pump connection Main pressure relief valve [16] Standard inlet section The inlet section is available in two basic versions: the conventional version and aversion with pump unloading. The conventional inlet section has two pump connections, P1 and P2, and a tank connection, T2.The direct-acting main pressure relief valve is also located in the inlet section. The F130 with closed centre (F130CP, F130LS) is created by combining inlet section I with L or CUI at item [26]. The difference between the F130CP and the F130CF is that the free-flow...
