Abstract: A valve, in particular a pilot-operated proportional directional poppet valve, has a valve housing (7) with a fluid inlet (21) and a fluid outlet (23). The fluid stream between the fluid inlet (21) and the fluid outlet (23) is adjustable by a main piston (27). A pilot valve chamber (37) on a rear face (29) of the main piston (27) has a pilot valve closing member (33) movable by an actuating device (69) to adjust the fluid stream between the pilot valve chamber (37) and the fluid outlet (23). A supply aperture (3) is between the fluid inlet (21) and the pilot valve chamber (37). The opening cross-section of the supply aperture (3) can be reduced by a control element (49).

Abstract: A pressure retaining valve (1) has a main control piston (39) guided longitudinally displaceably in a single-piece or multiple-piece valve housing (29) and a non-return piston (43). In a pressure retaining position, a fluid-conducting connection between connection points (37a, 37b, 21) is shut off by the two pistons (39, 43). Connection point (37a) serves to feed media. Connection point (37b) discharges media. Connection point (21) leads to a hydraulic consumer. In a load-raising position, the two pistons (43) move relative to one another into a release position, in which the connection between the medium feed (37a) and the consumer is established. In a load-reducing position, the two pistons (39, 43) assume a spacing from one another such that the connection between the medium discharge (37b) and the consumer is established. A monitoring device (75) determines the individual switching positions of the pistons (39, 43) to ensure reliable functioning of the pressure retaining valve (1).

Abstract: A valve, in particular for hydraulic circuits, includes a valve body (4) designed as a cartridge that can be fixed in a housing (6) having fluid connections (8) by a securing device (20, 26, 28). The securing device has at least one blocking element (20) in the form of a separate component between the valve body (4) and the housing (6). The blocking element has blocking surfaces that can be moved relative to the longitudinal axis (18) of the valve body (4) between an assembly position allowing the valve body (4) to be inserted into the housing (6) and a blocking position in which the blocking surfaces secure the valve body in an assembly position, preferably with zero backlash by bearing against retaining surfaces (26, 28) of the housing (6) and the valve body (4).

Abstract: The invention relates to a valve, in particular a proportional pressure regulating valve, comprising a valve housing (10) and a valve piston (12) which is arranged in the valve housing in a longitudinal a movable manner and which can be actuated by means of an actuation magnet (14) so as to produce either a fluidic connection between a pressure supply connection (P) and a load connection (A) or between the load connection (A) and a return connection (T) in the valve housing (10), wherein the valve piston (12) is permanently fluidically connected to the return connection (T) at the opposing end faces (44, 46) of the valve piston. The invention is characterized in that the valve piston (12) has a pressure-active measuring surface (50) in the region of the load connection (A), said pressure-active measuring surface providing the respective fluid pressure at the load connection (A) as a counterforce to the actuation force of the actuation magnet (14) when the actuation magnet (14) is energized in order to produce a fluidic connection between the pressure supply connection (P) and the load connection (A).

Abstract: A device includes a regulating piston (12) guided longitudinally movably in a housing (10) and interacting with a control edge (56), at a pressure supply port (P) that supplies a utility port (A) in regulating positions of the regulating piston (12) with fluid. The pressure can be preset via a fluid connection, pulling the regulating piston towards a closed position blocking this fluid connection due to occurring flow forces. The regulating piston (12) has a change of shape (60) from its general outer basic shape in the area of the control edge (56) of the housing (10) for a flow force compensation. A flow contact surface for fluid is provided causing a compensating force acting against the flow force to be introduced into the regulating piston (12), which flow force pulls the regulating piston (12) into an open position opposite from the blocked position. The change of shape (60) also follows a step function, the function graph of which has at least one step more than the number of steps required to form the control edge (56).

Abstract: A pressure-regulating valve has a valve piston (10) subjected to the action of an energy store and guided longitudinally in a valve housing (12). The valve housing has a supply port (14), a utility port (16) and a tank port (18) actuated by a control part (20) closing with a sealing action. In connecting from the supply port to the utility port, a pressure reduction function is realized. In a fluidic connection from the utility port to the tank port, a pressure-limiting function is realized. The control part (20) has a control rod (22) with two control bodies (24, 26) spaced apart from one another. One control body (24) controls the connection between supply port (14) and utility port (16). The other control body (26) controls the connection between utility port (16) and tank port (18).
