Abstract: A valve, in particular a pilot-operated proportional pressure control valve, has a valve housing (5) with a pressure supply port (7), a working port (9), and a drain port (11). In the valve housing (5), a main valve piston (15) can be moved by a pilot stage (13) for control of the fluid flow between the pressure supply port (7) and the working port (9). The pilot stage (13) has a valve closing element (43) for a pilot chamber (41). The valve closing element (43) is movable from an open position (OS) into a closed position (SS) by an actuating apparatus (45). The valve closing element (43) can actuate a leakage reduction stage (53).

Abstract: Device with hydraulic system actuates first and second hydraulic consumers. The hydraulic consumers (10, 12) can be supplied with fluid at a predefinable pressure at least via a flow divider (26) for dividing a fluid flow from a pressure supply (P) into predefinable part flows leading to the respective hydraulic consumer (10, 12). A fluid flow from the hydraulic consumer (10) with higher pressure loading via the flow divider (26) to the hydraulic consumer (12) with lower pressure loading can be suppressed by one shut-off device (38) arranged between the flow divider (26) and at least one hydraulic consumer (12). The shut-off device (38) is arranged in a fluidic connection (F2) from the flow divider (26) to the hydraulic consumer (12) with lower pressure loading.

Abstract: A valve has a valve piston (12) guided longitudinally movably in a valve housing (10) and actuated by an operation device (14). In one valve piston position, a connection is produced between a pressure supply port (P) and a working port (A). In another valve piston position, a further fluid-conducting connection is produced between the working port (A) and a tank port (T). The pressure difference arising between the working port (A) and the tank port (T) as flow passes through the further fluid-conducting connection acts, by an actuation device (30), on the valve piston (12). The valve piston passes from a stop position (32), with the further fluid-conducting connection shut off, into a fully open opening position with an enlarged opening cross section from working port (A) to tank port (T).

Abstract: A valve, in particular a 4/2-way slide valve (60), includes a valve piston (67), which is guided in a longitudinally movable manner in a valve housing (25), for selectively connecting and disconnecting fluid connections in the valve housing (25), such as a pressure supply connection (P), a tank connection (T), and two utility connections (A, B). A magnetic system (49), to which current can be supplied, controls the valve piston (67). When no current is supplied to the magnetic system (49), the control pressure at one of the utility connections (A, B) can be set, in particular limited, by a control device (62, 70, 79, 80, 88) arranged in the valve housing.

Abstract: A valve (18), for a valve assembly (10) for regulating the pressure of a fluid guided in a hydraulic system for supplying pressure to at least one hydraulic consumer (12a, 12b), includes a pilot control stage (48) and a main control stage (38) for at least partially clearing or blocking a fluid path from a supply connection (P) to an outflow connection (T). A relief stage (54) for pressure relief of a fluid chamber is arranged between the pilot control stage (48) and the main control stage (38). The relief stage (54) compares the existing load pressure at load terminal (LS) dedicated to the hydraulic consumer (12a, 12b) with the outflow pressure at the outflow connection (T), clearing the pressure relief if both pressures are approximately the same. The relief stage (54) can be directly connected to the load connection (LS) and can be charged with load pressure.
