Example fluid valves having non-circular flow passageways are disclosed. An example fluid valve includes a body defining a fluid passageway between an inlet and an outlet, at least a portion of the fluid passageway between the inlet and the outlet has a generally non-circular cross-sectional shape when taken along a plane transverse to a direction of fluid flow, the cross-sectional shape includes a curved central axis, with outwardly curved end walls and curved lateral walls joining the curved end walls.

A valve trim for use in a fluid flow control device. The valve trim includes a cage body defined by an outer cage wall and an inner cage wall coupled to the outer cage wall, the outer cage wall spaced radially outward of the inner cage wall. The valve trim also includes a plurality of first flow characterizing passages formed in the outer cage wall, and a plurality of second flow characterizing passages formed in the inner cage wall. The cage body is at least partially made of an erosion-resistant material.

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.

An electromagnetic control device and a gas valve are provided. The electromagnetic control device includes a sealing head, a sleeve, a first regulating part and a second regulating part. The sealing head is fixedly connected with the sleeve, a part of the sealing head is located inside the sleeve; the sealing head includes a first internal threaded portion, and the first regulating part includes a first external threaded portion; the first regulating part further includes a second internal threaded portion, the second regulating part includes a second external threaded portion. The electromagnetic control device further includes a damping part, the damping part is arranged between a threaded connection structure between the first regulating part and the sealing head, and the damping part is connected to one of the first regulating part and the sealing head.
