  • Patent number: 10634257
    Abstract: A proportional valve is provided wherein the valve has an actuating element, a compressed-air connection, a working connection, and an air-removal connection. The valve also has three valve elements arranged one after the other and each can be moved in an axial direction. A first valve element is actuated by the actuating element, a second valve element is actuated by the first valve element, and a third valve element is actuated by the second valve element. In a base position, the valve elements are spaced apart, and, within the valve, a first sealing seat effective between the first valve element and the second valve element and a second sealing seat effective between the third valve element and the housing are arranged such that by varying the position of the first valve element, different switching states can be set.

  • Patent number: 9807892
    Abstract: A drive unit is provided, particularly a drive unit for operating flow-control valves, comprising a housing, an electrical input, an electromechanical converter assembly, a mechanical output, and an electronic controller. The controller comprises an input unit having at least one pushbutton, which penetrates the housing and can be depressed against the action of a restoring device, and comprises a contactless switch that is actuated by the at least one pushbutton. A mechanical stop independent of the switch itself is associated with the position of the pushbutton that actuates the switch.

  • Patent number: 8973890
    Abstract: A fluid-operated actuating drive on a valve comprising a base unit (2) having an electro-fluidic signal converter and a fluidic controller and at least one linear actuator (4) that can be actuated using the fluidic controller, wherein the gate (11) of the linear actuator is directly or indirectly coupled to the inlet of the valve. A control unit (22) is connected to a signal input of the base unit, wherein the signal output is connected to the electro-fluidic signal converter. The actual value signal of a measurement transducer (24) associated to the valve is fed back to the control unit. A fluidic internal control circuit (27) is arranged functionally between the signal input and the at least one linear actuator, preferably downstream of the electro-fluidic signal converter.

  • Patent number: 8752806
    Abstract: A fluid-operated actuating drive (1) on a valve, in particular a shut-off, safety or regulating valve, comprising a base unit (2) having control valves, two linear actuators (6, 7) which are located opposite of each other and can be actuated fluidically, and a mechanical converter (5) which is arranged between the two linear actuators and couples the gates thereof to each other, wherein the outlet of the converter is coupled to the inlet of the valve. To this end, the actuating drive is composed in a modular manner of individual components joined to form a functional unit in the form of the base unit, the two linear actuators and the mechanical converter.

  • Patent number: 8220491
    Abstract: A piezoelectric valve having a housing is provided with an inner chamber, in which ends at least one nozzle communicating with an associated port for a medium and provided with a sealing seat having a seat face, a deformable piezoelectric bending element being received in the inner chamber of the housing in such a way that the nozzle can be closed by a portion of the bending element movable relative to the nozzle in response to deformation of the bending element, and the bending element being provided with padding of an elastically resilient material, at least in its region opposite the nozzle. This sealing seat is disposed at the end face of a nozzle insert, which is disposed to be displaceable substantially perpendicular to the seat face in a receptacle fixed to the housing, a thermally expandable compensating member acting between the receptacle and the associated nozzle insert.
