Abstract: A stator unit includes a main circuit board parallel to an up-and-down direction, a sub circuit board at a right angle to the main circuit board, a magnetic sensor on the sub circuit board, and a housing including a sub circuit board space that is located adjacent to an inner space of the stator unit in which a can is disposed. The sub circuit board includes a first end connected to the main circuit board via a circuit board terminal and a second end located near the inner space in the sub circuit board space. The magnetic sensor is located closer to the inner space than the circuit board terminal is.

Abstract: An electromagnetic-mechanical locking device applied to a subsurface safety valve comprising an electromagnetic-mechanical coupler formed electromagnet (4), ferromagnetic bulkhead (5) in solidarity to the mobile part (6), actuated by spring (9), in addition to locking element (7), and when activated, the electromagnet (4) creates a magnetic field that attracts the ferromagnetic bulkhead (5), along with the mobile part (6), moving this set towards the electromagnet (4), and compressing the locking element (7). During the movement, the mobile part (6) shifts the locking element (7) to the locking position, until it reaches its coupling on the flow tube (3), where it is maintained with compression locking element (7), configuring a trigger device. When the power supplied to the electromagnet (4) ceases, the electromagnetic attraction force of the ferromagnetic bulkhead (5) is cancelled, and the locking element (7), until then retracted, is distended, causing the return of the mobile part (6) to initial position.

Abstract: A pressure and vacuum generating module for a carrier transport system includes a combined blower, air chamber and rotating valve module which alternately couples a pressure chamber and a vacuum chamber to the carrier transport system, creating high or low pressure regions which move a transport carrier. The valve repositions a baffle which blocks one or the other of the chambers, or both chambers, the latter for breaking and landing of the carrier. With a chassis that includes the blower motor, air chamber and valve, the module is adapted for new construction as well as for retrofitting and replacing older legacy blower modules.

Abstract: A valve body device includes a valve body assembly including a feed flow path and a plurality of discharge flow paths, and a valve core assembly rotatably provided at the valve body assembly and having a reset position and a plurality of working positions along a rotating direction. Each working position corresponds to a discharge flow path. When the valve core assembly is at a working position, a discharge flow path corresponding to the working position communicates with the feed flow path. The valve body device further includes a drive assembly configured to drive the valve core assembly to rotate and including a position detection assembly configured to generate reset information when the valve core assembly is at the reset position, and a detection assembly configured to detect rotation information of the drive assembly and determine a rotating angle of the valve core assembly based on the rotation information.

Abstract: A water delivery control system operates to selectively deliver water from a water source to water use devices. The system includes at least one controller that wirelessly communicates messages with a portable user device. The system includes a water control valve and a motor that is operative to selectively move at least one valve element of the valve. A water meter is operative to measure water flow that corresponds to flow through the valve. The controller is operable to cause the valve to enable or prevent flow through the valve responsive at least in part to water flow data. The controller is operative to determine a water use condition responsive to a water usage pattern, and to cause at least one message to be sent to the portable user device responsive to the determined water use condition.

Abstract: A fail-safe drive (1) for an actuating drive is provided, which has a cam disc (8), at least one restoring element, a counter-element (5) and an output shaft (3), with the cam disc (8) and the counter-element (5) being configured for joint conversion of an axial movement of the restoring element along the output shaft (3) into a rotational movement of the output shaft (3). The cam disc (8) has a control cam (10), the profile of which is adapted to a spring characteristic curve of the restoring element such that, in the case of activation of the failsafe drive (1), a constant output movement and/or a constant output torque can be generated.

Abstract: Provided is a flow rate control device capable of suppressing variation of supply pressure caused by variation of set flow rate and suppressing influence of pressure loss and cavitation on a secondary side. The flow rate control device (18) includes: a flow rate regulating valve (19) that regulates a flow rate of fluid flowing in a flow path; a flow meter (20) that measures the flow rate of the fluid flowing in the flow path; and a control portion (21) that controls an opening degree of the flow rate regulating valve (19) based on a measurement result of the flow meter (20), the flow rate regulating valve (19) is a three-way valve for dividing to regulate fluid flowing in from an inflow port (24) to a first outflow port (25) and a second outflow port (26), the flow meter (20) is connected to the second outflow port (26) side, and a multistage throttle orifice (22) for decompressing the pressure of the fluid in stages is provided on the first outflow port (25) side.

Abstract: For improving manual operation of an actuator (1), a novel clutch (4, 6) is proposed that features at least one movable protrusion (12) that is axially movable along a coupling axis (11) of the clutch (4, 6) relative to an element (8) that carries the protrusion (12). This design has the advantage that engagement of the clutch (4, 6) is possible under all circumstances, even in cases in which the protrusion (12) is not yet in a correct rotational coupling position (18) (cf. FIG. 7 ), as the protrusion (12) can be transferred into the coupling position (18) by a rotational movement (24, 25) at all times.

Abstract: A valve operating device includes a base having a housing thereon. A motor, a motor controller unit, and a human machine interface controller are disposed in the housing. A display device mounted on top of the housing is controlled by the human interface controller to display control screens and receive user input. The operator controls operation of the device at a home control screen, which displays information regarding the exercise of the valve as it is acquired. Data configuration and storage functions are controlled via a valve data record screen and identifier screens accessible from the home control screen.

Abstract: A valve operating device includes a defining a transverse axis extending from a first end to a second end. A motor is positioned within the housing. The motor includes a motor output shaft configured to drive at least one gear disposed within the housing. The at least one gear is configured to rotate a key extending substantially perpendicular to the transverse axis to engage a valve. A motor controller unit drives the motor in either a clockwise or a counter-clockwise direction at a variable motor speed to deliver up to a torque limit. A user interface comprises a first motor activation throttle configured to drive the motor in the clockwise direction at a user-controlled speed when activated. A second motor activation throttle drives the motor at a user-controlled speed in the counter-clockwise direction when activated.
