A thermostatic valve includes a valve body formed by die casting. The valve body includes: a valve main body forming a valve cavity; a plurality of connection tube portions; and installation base portions adjacent to the connection tube portions. Each of the connection tube portions includes a straight tube section connected to the valve main body. A reinforcement member is provided between the straight tube section of the connection tube portion and the installation base portion adjacent to the connection tube portion. The valve body is formed by die casting, and respective parts of the valve body can be processed according to actual size requirements with no redundant material, thereby realizing a light weight of the thermostatic valve. Providing the reinforcement member satisfies a strength requirement when using die casting.

A valve device is capable of precisely adjusting a flow rate variation with time, aging, or the like without using an external sensor or using as few external sensors as possible. The apparatus includes an adjusting actuator for adjusting the position of the operating member positioned at the open position, a communication unit for receiving adjustment information relating to the adjustment of the opening degree of the flow path by the valve element from the outside of the apparatus, and a control unit for adjusting the position of the operating member by driving the adjusting actuator based on the adjustment information.

The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) which comprises a closing element (14) that is arranged therein and can be moved in the longitudinal axis (18). The closing element (14) interacts with a seal seat (16) in order to release and close a through-opening (22). The valve housing (6) is equipped with at least one spring element (8) which is supported against the closing element (14) and the valve housing (6). Furthermore, the at least one spring element (8) is made of a bimetal.

A fluid control system for supplying fluid to a fluid consumer, having a valve module including a channel body to which a fluid switching valve, a fluid pressure regulator and a vacuum switching valve are attached, the channel body having a first fluid channel extending from a fluid input port to an input port of the fluid pressure regulator and having a second fluid channel extending from an output port of the fluid pressure regulator to an input port of the fluid switching valve, and having a third fluid channel extending from an output port of the fluid switching valve to a fluid consumer port, and having a first vacuum channel extending from a vacuum input port to an input port of the vacuum switching valve, and having a second vacuum channel extending from an output port of the vacuum switching valve to the fluid consumer port.

A servo valve comprises a first spool extending along a first spool axis, a second spool extending along a second spool axis, a first piezoelectric actuator, and a second piezoelectric actuator. The first piezoelectric actuator is operatively connected to the first spool for translating the first spool in response to a voltage applied thereto. The second piezoelectric actuator is operatively connected to the second spool for translating the second spool in response to a voltage applied thereto.

A bar valve includes an elongate housing having a first inlet located towards a first end of the housing, a second inlet located towards a second end of the housing, and an outlet located between the first inlet and the second inlet. A mixing chamber is located within the housing, the mixing chamber being configured to receive first and second input flows from the first inlet and second inlet, respectively. A flow controller is configured to receive a mixed flow from the mixing chamber and controllably output an outlet flow to the outlet. The mixing chamber and flow controller is disposed sequentially in a region of the housing between the first end and the outlet, thereby confining the mixed flow and the outlet flow to the region of the housing between the first end and the outlet.

A valve control assembly includes a valve body having an inlet adapted to be coupled to a source of process fluid having a first temperature, an outlet, and a fluid flow path extending between the inlet and the outlet, and a bonnet coupled to the valve body. An inlet port, an outlet port, an annular plenum, an inlet passage, and an outlet passage are integrally formed in the valve body or the bonnet. The inlet port is adapted to be coupled to source of media and the annular plenum is disposed between the inlet port and the outlet port, immediately adjacent a portion of the fluid flow path. The inlet passage directs the media from the inlet port to the annular plenum, which changes a temperature of the process fluid flowing through the fluid flow path from the first temperature to a second temperature different from the first temperature.
