Valve systems and related methods include valve actuators and control systems configured to monitor at least one characteristic of the valve system during movement of a valve element to a position in the valve system and to determine a drift of the position based on the monitored at least one characteristic of the valve system.

The present invention is an improved fluid valve control device which attaches to a pre-existing and pre-installed hex head valve. The valve control device has at least one lever which can be used to turn the valve on or off. This device can be attached to a manifold assembly that has a valve which typically requires a tool to control so that it eliminates the need for a separate tool being used to turn the valve on or off after installation at relatively low cost.

A faucet with integrated manual and automatic flow control, which includes a faucet body, a valve, a handle, a cold water inlet pipe, a hot water inlet pipe, a water outlet pipe, a sensing unit and a control device. The valve and the control device are both arranged inside the faucet body. The handle is arranged on one side of the faucet body and is connected with one end of the valve, the other end of the valve is connected with the control device. The sensing unit is arranged on the faucet body and is electrically connected with the control device. The cold water inlet pipe and the hot water inlet pipe are both connected to one end of the water outlet pipe through the valve.

A reservoir refill system for an electronic vaping device includes a refill container and a reservoir. The refill container contains a pre-vapor formulation. The refill container includes a body, an opening in the body, and a first interlocking ring including at least one groove or at least one protrusion therein. The reservoir is configured to contain a pre-vapor formulation and includes a reservoir body, an opening in the reservoir body, and a second interlocking ring including at least one groove or at least one protrusion therein at an opening of the reservoir. The first interlocking ring is configured to mate with the second interlocking ring so as to release the pre-vapor formulation from the refill container to the reservoir.

A control valve assembly includes a valve body defining an inlet, an outlet and a fluid flow pathway therebetween. A ball valve is positioned within the fluid flow pathway and includes a rotatable ball having an inlet opening, an outlet opening and a flow pathway therebetween, an upstream seat ring positioned at an inlet side of the ball, and a downstream seat ring positioned at a downstream side of the ball, the seat rings being configured to substantially seal off fluid flow between upstream and downstream sides of the ball except through the ball fluid flow pathway. At least one of the upstream and downstream seat rings is a dynamic sealing seat ring. A retainer ring is positioned between the dynamic sealing seat ring and a portion of the rotatable ball to substantially prevent deformation of a portion of the dynamic sealing seat ring in a direction toward the ball.

The present disclosure relates to an adjustable covering trim for covering a valve concealed behind a finishing wall and which is adapted to accommodate different valve installations. The trim includes a decorative outer frame to be mounted on a finishing wall, a handle which is rotatably coupled thereon and an articulated cartridge adaptor or interface which can be releasably coupled with an internal surface of the hollow handle. The adaptor is further adapted to be mounted on a cartridge distal end of the valve so that both the cartridge distal end and the articulated cartridge adaptor can rotate with the hollow handle upon rotation of the hollow handle about a cartridge centerline. The articulated cartridge adaptor is articulable relatively to the cartridge centerline. The covering trim may further include a temperature control mechanism and means to easily mount a decorative cover to the finishing wall.

An installment method of a fluid control body and a fluid control device including a fluid control body with which processes of designing, manufacturing, and managing the fluid control body are simplified to suppress cost of manufacturing, etc, includes a cut-off step of cutting off part of a fluid pipe inside a casing, and an installment step of installing the fluid control body including an on-off valve formed by a valve seat body and a valve element, and a partition body formed by a wall portion, a lid portion, and a seal component, inside the casing in a sealed manner in a state where an operation shaft of the on-off valve is placed in a direction different from the vertical direction.

A new and innovative high-pressure priming valve is provided for use in high-pressure fluid systems that require a high level of fluid purity. The priming valve includes at least three ports, some of which are angled. The priming valve also includes a needle that variably blocks and unblocks a pathway to one of the ports between normal operation and a priming operation, respectively. The priming valve includes a sealing insert positioned below a stack of washers that maintain the needle's alignment in response to high fluid pressures exerted on the needle. The sealing insert helps prevent fluid from contacting the stack of washers, which helps prevent biological growth within the valve. The angled ports help facilitate priming valve drainage to further help prevent biological growth. By helping prevent biological growth, the sealing insert helps prevent fluid contamination and enables the priming valve to be utilized for high-purity fluid applications.
