In order to provide a piezo valve in which it is possible to accurately predict the remaining lifespan of a piezo actuator, there are provided a valve seat, a valve body that is able to move between a fully closed position in contact with the valve seat and a fully open position, a piezo actuator that drives the valve body, a drive circuit that receives an input signal, and outputs to the piezo actuator a corresponding drive voltage, and a leakage current detector that, when the drive circuit outputs a voltage equal to or greater than a maximum rated voltage that drives the valve body to the fully closed/open position, detects leakage current from the piezo actuator. When the leakage current is detected or in a state immediately prior to detection, a fluid is flowing between the valve seat and the valve body.

A valve assembly including a valve arranged to move between open and closed positions by rotating an operating member about an axis is provided. An actuation unit includes a torsion spring, a trigger member, and a driving member. The driving member engages with the operating member to drive rotation of the same. The torsion spring applies a first torque to the driving member around the axis in a first rotational direction. An external second torque opposite the first torque resets the valve to the open position in which the driving member is held by a latching mechanism. The latching mechanism is arranged to hold the driving member only when the valve is in the open position. An external force applied to the trigger member releases the driving member from the latching mechanism, the first torque thereby rotating the driving member to mechanically bias said valve to the closed position.

An assembly having a coupling component and a poppet is disclosed. The coupling component has a first end. The first end has an opening extending into the coupling component, such that the coupling component has a sidewall extending around and defining the opening, the sidewall at least partially constructed of a ductile material. The poppet is positioned within the opening. The poppet has a first end outside of the opening, a second end within the opening, and an outer surface extending between the first end and the second end. The poppet has a recess positioned between the first end and the second end, the recess being defined by at least one sidewall and a bottom. At least a portion of the ductile material of the sidewall is positioned within the recess to secure the poppet into the opening.

In one embodiment, a non-transitory computer readable medium may include computer-executable instructions that, when executed by a processor, may cause processor to receive a set of user data associated with a user that is attempting to access an electronic lock, receive a request to actuate a locking mechanism of the electronic lock configured to prevent the user from accessing a machine in an industrial automation system, actuate the locking mechanism in response to the request and the set of user data corresponding to an expected set of data, store a log of the request and the set of user data, and send the log to a cloud-based computing system.

Provided is a flow rate control valve capable of suppressing leakage of a fluid when the flow rate control valve completely closes a valve port as compared to a flow rate control valve that does not include a gap reducing portion being provided so as to partially reduce a gap between a valve body and a member opposed to the valve body, and a temperature control device using the flow rate control valve. The flow rate control valve includes: a valve main body including a valve seat, the valve seat having a columnar space and having one or a plurality of valve ports, which allow a fluid to flow therethrough and each have a rectangular cross section; a valve body being provided in a freely rotatable manner in the valve seat of the valve main body so as to open and close the one or the plurality of valve ports, the valve body having a cylindrical shape and having an opening formed in an outer peripheral surface of the valve body; a gap reducing portion being provided so as to partially reduce a gap between the valve body and a member opposed to the valve body; and drive means for driving the valve body to rotate.

A micro-valve includes an orifice plate having a first surface, a second surface and an orifice extending from the first surface to the second surface. An actuating beam is disposed in spaced relation to the orifice plate. The actuating beam includes a base portion and a cantilevered portion. The base portion is separated from the orifice plate by a predetermined distance. The cantilevered portion extends from the base portion such that an overlapping portion thereof overlaps the orifice. The actuating beam is movable between a closed position and an open position. The micro-valve also includes a sealing structure including a sealing member disposed at the overlapping portion of the cantilevered portion. When the actuating beam is in the closed position, the cantilevered portion is positioned such that the sealing structure seals the orifice so as to close the micro-valve.

A drain valve for a sterile container includes: a valve housing; a bypass that connects a container gas volume with an external gas volume; a valve body that blocks the bypass; and an actuator that displaces the valve body between a passage position and a blocking position. The valve body is displaceable according to a temperature and/or a pressure of the bypass gas volume. The valve housing has: at least one holding web, at least part of which can be located in a holding bracket of the valve receptacle; and a closure. The valve housing is pivotable from an open position into an installation position in which the closure can be fixed to a closure receptacle. When the valve housing is transferred into the installation position, the valve body is transferred into the blocking position and subjected to a closure force.

A method of operating a vehicle includes navigating the vehicle along a path, collecting a set of navigation parameters of the vehicle from at least one of a sensor, a global positioning system, or an inertial reference system, determining a set of statistical uncertainties related to at least some navigation parameters in the set of navigation parameters, and associating a set of statistical weights to the at least some navigation parameters.

Provided is a downsizable valve unit. A valve unit 1 includes a valve case 4 including a valve case main body 4A where a thermo valve 2 is housed and a valve seat 4Aa which a valve body 2b unseats from and seats on is formed, and a sleeve 4B formed protruding outward from the valve case main body 4A; a sub-flow path R2 formed to include a cooling water storage chamber S formed inside the sleeve 4B, a lead-out passage 4Ae communicating the upstream side of the valve seat 4Aa in the valve case main body 4A with the cooling water storage chamber S, and a lead-in passage 4Af communicating the downstream side of the valve seat 4Aa in the valve case main body 4A with the cooling water storage chamber S; and a sub-valve 3 attached to a sleeve 4B to open and close a sub-flow path R2.
