A control valve (2) for regulating a fluid flow in an HVAC comprises a valve body (21) and a temperature sensor (25) configured to measure the temperature of a fluid (24) flowing within the control valve (2). The temperature sensor (25) is arranged such that the temperature sensor (25) is essentially thermally decoupled from the valve body (21).

A backflow prevention assembly includes a body forming two buckets, wherein flow passes through the body from an inlet to an outlet along an axis and consecutively through each of the buckets. A single zone test cover encloses a first of the buckets to form a single zone chamber. A dual zone test cover encloses a second of the buckets with a dual zone cartridge assembly therein. The dual zone test cover has two test cocks. The dual zone cartridge assembly includes a frame having a valve seat, wherein the frame includes a lumen providing fluid communication from a dual zone chamber upstream of the valve seat to a first of the two test cocks of the dual zone test cover, and wherein the second of the two test cocks of the dual zone test cover is in fluid communication with the dual zone chamber downstream of the valve seat.

The disclosure provides a method for testing a solenoid valve for triggering a safety valve having a single-acting fluidic drive and a positioner. The drive fluid pressure is increased by a first pressure difference. An attempt is made to switch the solenoid valve to the safety position. The drive fluid pressure is measured at a specified point in time that is selected such that the pressure in the drive fluid lowers at most by the first pressure difference. If the pressure in the drive fluid is higher than a reference pressure at the specified point in time, the functionality test of the solenoid valve is failed. The lowering of the pressure in the drive fluid is monitored over a defined period of time to make conclusions regarding the pressure generating system. The pressure does not fall below the operating pressure so the position of the valve member remains constant.

A system includes a mounting panel having diffusion-bonded metal plates that form a reservoir to contain a process fluid, multiple channels through which to flow the process fluid, and vias through which to flow the process fluid to and from process fluid control components attached to the mounting panel. At least a pair of the multiple channels are connected with the reservoir. A temperature sensor is attached to a top of the mounting panel, the temperature sensor in fluid communication with the reservoir through one of the vias. A set of inlet ports are attached to the mounting panel, the set of inlet ports to receive the process fluid. At least one outlet port is attached to the mounting panel, the at least one outlet port to output the process fluid from the mounting panel.

An electronic expansion valve and a manufacturing method therefor, a thermal management assembly and a cooling system are provided. The electronic expansion valve includes a valve core assembly, an electronic control part and a stator assembly. The valve core assembly includes a valve base, a valve core and a rotor assembly, wherein the valve base is provided with a valve port, and the valve core moves relative to the valve base to change the degree of opening of the valve port. The electronic control part controls the stator assembly, and the rotor assembly drives the valve core to move. The electronic expansion valve further includes a sensor, the electronic control part includes an electronic control board, and the stator assembly and the sensor are both directly electrically connected to the electronic control board. The thermal management assembly and the cooling system both include the electronic expansion valve.

A fluid-dynamic device with integrated sensor element includes a first chamber suitable for the containment and/or the passage of a fluid, provided with an inlet opening operatively connectable to a fluid-dynamic circuit and configured to allow a fluid to enter the first chamber, and with a separate outlet opening, operatively connectable to a fluid-dynamic circuit and configured to expel said fluid from the first chamber. The first chamber includes at least one portion elastically deformable due to the action of the fluid contained therein and/or passing through the first chamber, to which a sensor element is associated which is sensitive to the deformation of the elastically deformable portion of the first chamber.

Embodiments of the present disclosure relate to a choke valve that includes a choke body, a choke trim disposed in the choke body, where the choke trim is configured to adjust a cross-sectional area of a flow path in the choke body to adjust a fluid flow through the choke valve, a needle of the choke trim disposed in the flow path of the fluid flow, where the needle includes a first portion having a superhard material, a seat of the choke trim, where the needle is configured to move along an axis extending through an opening of the seat to adjust the fluid flow through the choke valve.

A monitor device that is configured for use on flow controls and like industrial devices. The embodiments may include a resonator that is sensitive to vibrations on the flow control. The resonator may generate a non-electrical signal, like pressure waves. This non-electrical signal can transit a conduit to a sensor that can convert the pressure waves into an electrical signal. On valve assemblies, a controller can process the electrical signal to detect potential health or maintenance issues. The controller may, in turn, generate an alert to prompt operators to perform maintenance on the flow control.

A housing assembly for a manifold includes a first housing with an inlet and a plurality of outlets, a second housing, and a valve retainer engaged with the first and second housings. The valve retainer includes a retention plate defined between first and second surfaces, a plurality of slot walls extending from the first surface, and a protruding edge that extends from a flanged lip and surrounds the plurality of slot walls. The retention plate defines a plurality of slots corresponding to the plurality of slot walls. The first housing may define a groove that receives the protruding edge, and the second housing may include a rim that engages the flanged lip of the valve retainer. Valve housings including first and second mating structures separated by wall segments may be positioned in outlets of the first housing and corresponding slots of the valve retainer.

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.
