Various devices and techniques related to magnetically-actuated valves are generally described. In some examples, magnetically-actuated valves may include an asymmetric torque magnetic valve actuator effective to generate a first amount of torque when disposed in a first orientation and a second amount of torque when disposed in a second orientation. In some other examples, the valves may include mechanical stops that prevent binding of the valves in a closed or open position.

Various devices and techniques related to magnetically-actuated valves are generally described. In some examples, valves may include a valve body with a cavity. Valves may include a stem at least partially disposed in the cavity. Valves may include a valve member coupled to the stem. Valves may include a ferromagnetic actuation member disposed in the cavity. The ferromagnetic actuation member may be operatively coupled to the stem such that movement of the ferromagnetic actuation member actuates movement of the valve member between an open position and the closed position. Valves may include an actuator exterior to the valve body. The actuator may include a first magnetic pole section and a second magnetic pole section. A magnetic flux may flow from the first magnetic pole section through the ferromagnetic actuation member to the second magnetic pole section in a magnetic flux path through the interior portion of the valves.

Technologies are described herein for a check valve. The check valve can be operated using a lever and bellows system or an external magnet. External magnets external to the check valve move from a first position to open the check valve to a second position to close the check valve through the interaction of the magnetic fields of the external magnets and the internal magnet.

A grid valve may include an annular stationary plate having a first annular surface, and an annular rotatable plate disposed on the annular stationary plate and rotatable relative to the annular stationary plate. The annular rotatable plate may have a second annular surface, and each of the annular stationary plate and the annular rotatable plate may define a plurality of holes in the respective annular surfaces thereof. The grid valve may further include a first magnet disposed on the first annular surface and a second magnet disposed on the second annular surface such that the first magnet repels the second magnet.

The present invention discloses a non-contact flow control system having a totally sealed cavity, comprising a housing, a flow control unit and an operation unit. The housing is provided with a fluid inlet, a fluid outlet, and a fluid channel extending between the fluid inlet and the fluid outlet; the flow control unit is arranged in the fluid channel and the operation unit is arranged on an outer side of the housing, wherein the operation unit comprises an operation element and an outer magnet fixed on the operation element; the flow control unit comprises a flow control element and an inner magnet fixed on the flow control element; when the operation element moves relative to the housing, the flow control element can move under the action of a magnetic force between the outer magnet and the inner magnet, thereby changing the flow of the system.

An attachment system comprises an attachment assembly having a side with an exposed surface. A magnetic structure comprises a plurality of assembly field emission sources having positions and polarities relating to an attachment spatial force function. A plurality of assembly pole pieces are coupled to the magnetic structure such that a spatial spacing is created between the magnetic structure and the side. Each assembly pole piece is coupled to a corresponding one of the plurality of assembly field emission sources for directing magnetic flux. An attachment target attaches to the exposed surface based on the attachment spatial force function. The attachment target comprises a plurality of target field emission sources having positions and polarities relating to the attachment spatial force. The attachment spatial force function is in accordance with a code and corresponds to the relative alignment of the plurality of assembly field emission sources and the plurality of target field emission sources to each other.

Apparatus and associated methods relate to a valve having an actuator configured to translate a mass in a plane and a valve element located out of the first plane and configured to translate along a first linear axis. In an illustrative example, at least one of the mass and the valve element may include a magnetic source providing a persistent magnetic field and the other may include a non-magnetized, magnetically permeable mass. Reluctance-induced forces may, for example, translate the valve element towards the mass along the first linear axis when the mass is brought into register with a second linear axis. The first linear axis and the second linear axis may, for example, be colinear. Various embodiments may advantageously provide a valve requiring low energy input for operation.

A device for draining a liquid from a first film layer which forms at least one part of a building cladding element. A first valve element can be arranged in the region of a first opening of the first film layer such that the valve element can be pivoted between a first position, which closes the first opening, and a second position, which at least partly releases the first opening. Additionally, a first opening and closing are configured to keep the first valve element in the first position if pressure of a liquid is less than or equal to a threshold, allow the first valve element to pivot from the first position to the second position if the pressure of the liquid exceeds the threshold, and pivot the first valve element from the second position to the first position if the pressure is substantially no longer present.
