  • Patent number: 10704705
    Abstract: A sectional valve includes a working valve and a control valve, which controls the working valve. In order to permit a greater flexibility with respect to possible settings and/or use or operation by comparison to known solutions, it is proposed, for example, that the control valve have a control spring (34, 34?), which presses the anchor (5) onto the control valve seat (17), and against which the control coil (26) lifts the anchor (5) from the control valve seat (17), a permanent magnet (29), which in an actuation state is configured to hold the anchor (5) lifted from the control valve seat (17) by the core (35), and a magnet holder (28), in and/or on which the permanent magnet (29) is held in the actuation state, and which permits a distance from the permanent magnet (29), and/or that the control valve is configured to variably position the core (35) along a force generated by the control spring (34, 34?).

  • Patent number: 10677374
    Abstract: A limit switch assembly, for a rising-stem valve having a stem with a diameter and a groove marking a desired stem position, includes an actuator arm having an inner end and an outer end. The inner end of the actuator arm forms a follower. A radius washer is mounted to the outer end of the actuator arm. An electrical switch has an operating lever and is mounted adjacent to the outer end of the actuating arm such that when the actuator arm is in an outward position the radius washer moves the operating lever, operating the electrical switch. When the actuator arm is in an inward position the radius washer does not move the operating lever and the electrical switch is not operated.

  • Patent number: 10648587
    Abstract: A fluid valve incorporates a plunger with a fluid channel. The plunger is connected to a boss coupled to a diaphragm, this boss also includes a fluid channel and the plunger and boss fluid channels are in fluid communication. The boss fluid channel opens to the backside of the diaphragm in the valve cavity and permits substantially complete pressurization or evacuation of the volume behind the diaphragm in the valve. The substantially complete pressurization of the volume behind the diaphragm enables full closure of the diaphragm and improves contact of the diaphragm with the valve seat thereby improving performance of the valve.

  • Patent number: 10626996
    Abstract: An electromagnetic valve, in particular for a motor vehicle air spring system, has a valve closing body which, in its basic position, shuts off a valve outlet and, for this purpose, is pressed against a valve seat by a restoring spring. To assist the opening process, a valve spring is also provided. The valve spring is supported at one side on a valve seat body and at the other side on a spring pot, which is arranged on the valve closing body. Preferably, a tubular section of the spring pot bears, non-displaceably in a lateral direction, directly against the valve closing body. An elastic sealing element may either be arranged on the end side of the valve closing body, or held laterally by a section, which forms an enclosure, of the spring pot.

  • Patent number: 10626997
    Abstract: A valve for use in a heating or cooling water circuit includes a housing that forms a feed line and a discharge line, and an adjusting unit that is formed separate from the housing and penetrates into the housing for adjusting a flow rate through the valve. The adjusting unit has a valve closing body which is operatively connected to a valve tappet in such a way that the valve closing body together with a valve seat body that in the intended operation is stationary in relation to the housing, forms a valve gap which is adjustable by axially moving the valve tappet. The valve is designed such that the valve gap in the intended operation, when the valve tappet is not actuated, is closed by closing forces and when the valve tappet is actuated in order to open the valve gap, these closing forces have to be overcome.
