A faucet configured to discharge ozone water comprises a faucet body, a water mixing valve mechanism, a water processor, a control switch, a processor, a control valve, and a detector configured to detect whether water is flowing through the detector. The faucet body comprises a faucet outlet, and the water mixing valve mechanism comprises a cold water inlet connected to a cold water resource, a hot water inlet connected to a hot water resource, and a mixed water outlet. The water processor comprises a water processing passage and an ozone generator connected to the water processing passage. The control valve is disposed between the cold water resource and an inlet of the water processing passage, and an outlet of the water processing passage is connected to the faucet outlet. The detector is disposed between the mixed water outlet of the water mixing valve mechanism and the inlet of the water processing passage, and the processor is electrically connected to the control switch, the ozone generator, the detector, and the control valve to close the control valve and the ozone generator when the detector detects the water flowing through the detector.

A valve positioner for use on a process control valve or “valve assembly.” The process control valve may include a pneumatic actuator and a valve having a closure member coupled with the pneumatic actuator and moveable relative to a seat. The valve positioner may couple to the pneumatic actuator to provide a pneumatic signal to set a position of the closure member relative to the seat. An accelerometer may couple with the valve positioner. The accelerometer may generate data in response to orientation of the valve positioner. In one implementation, the configurations can use this data to ensure proper visualization of data on a display. The data also permits the device to properly manage operating modes, like tight shut-off or fully-opened mode, that may prevail due to orientation issues that cause defects in a measured position for a closure member that regulates flow of material through the valve assembly.

The embodiments disclosed herein relate to an apparatus for monitoring a valve having a control element, wherein the control element is actuated by an actuator, having: an adaptor between the control element and the actuator, wherein the adaptor couples a valve stem of the control element to the actuator; and an electronics module contained within the adaptor, wherein the electronics module further comprises one or more sensors.

A two-dimensional motor and a servo valve are provided. The two-dimensional motor includes a stator and a rotator arranged coaxially. The stator is enclosed in the rotor. The stator and the rotor are spaced along a radial direction of the rotor. A size of the stator along an axial direction is greater than a size of the rotor along the axial direction. The rotor is, without bearing support, directly connected to an external mechanism. The rotor is swung at a predetermined angle, such that the external mechanism can drive the rotor to move along an axial direction of the rotor relative to the stator.

A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

A diaphragm assembly for a pressure relief valve can include a disc guide that is configured to receive a portion of a disc holder, a bonnet adapter, and a diaphragm that is clamped at an outer edge between the disc guide and the bonnet adapter. The diaphragm assembly can be positioned between a bonnet of the pressure relief valve and a valve body of the pressure relief valve to convert the pressure relief valve to a backpressure-balanced pressure relief valve by counterbalancing a backpressure that acts upon the disc holder.

A flow resistance insert of a flow rate measuring or flow rate control has contiguous discs between which at least one central axial flow duct is formed from which radial flow ducts branch off. The discs include alternating first discs and second discs. While the first discs are circumferentially closed ring discs, the second discs are circumferentially slotted one-piece ring discs.

An apparatus comprises a mounting panel including a top plate having multiple vias and multiple orifices. An internal face of the top plate includes a first cut-out region and channels through which to flow a process fluid. The first cut-out region can be a reservoir in which to contain the process fluid. The multiple vias are adapted for passing the process fluid through the top plate. The multiple orifices are adapted for attaching a plurality of process fluid control components to the mounting panel. An inner plate also has multiple additional vias. The apparatus includes a bottom plate, where the inner plate is compacted between the top plate and the bottom plate to form an integral metallic body in which to contain and flow the process fluid.

A valve for controlling the circulation of a fluid, having a valve body comprising a movable control member, an electrical actuator comprising a stator and a rotor, a sealing cover extending from the valve body to the inside of the stator, the sealing cover being positioned at the interface between the rotor and the stator in such a way that the rotor is inside the cover and submerged in the fluid, the stator being isolated from the fluid, the rotor rotating about a first axis and being secured to a shaft extending along the first axis, the movable control member moving in a linear manner along a second axis or in rotation about the second axis, characterized in that the shaft has an end forming, with a toothed wheel driving the movable control member, a gear pair with non-intersecting or intersecting axes.

A method for detecting a position of a signal generator in a position measuring system which includes at least one Hall sensor, a set of position intensity data is provided for a plurality of predetermined positions. A current measurement signal is detected for each measuring direction at the one Hall sensor or at each of the several Hall sensors for a current position of the signal generator, and the current position of the signal generator is determined from the position intensity data and all current measurement signals. The position intensity data for the position measuring system is stored in a control unit.
