A diaphragm valve structure having application in diaphragm valves made completely from fluororesin at an operating temperature of 200° C. The diaphragm valve uses a heat isolation method that consists of a heat transfer limiting structure and a heat dissipating structure, ensuring rigidity of the gas cylinder structure. The heat transfer limiting structure uses lattice-shaped ribbed plates with horizontal openings, wherein the lattice-shaped ribbed plates and a minimum diameter area of an annular portion are all provided with heat transfer section thickness. The heat dissipating structure consists of a multilayered structure for a preferred external natural cooling, and further using a coolant gas ensuring that the peripheral portion of the diaphragm and gas-tight components on the valve shaft are sufficiently cooled.

A valve including a valve body. An actuation housing of the valve body surrounds an actuation cavity. The actuation housing includes a first port configured for entry of actuating air and a second port configured for exhausting the actuating air. A poppet is configured for movement within the valve body and includes a barrier located within the actuation cavity. The poppet being actuated to an open position using the actuating air entering in the first port. When the poppet is in the open position, the actuating air flowing between the first port and the second port cools the stem.

A temperature control unit that controls a temperature of a gas valve and includes: a heat sink attached to the gas valve; and a housing that covers the heat sink and includes an introduction port through which a temperature control fluid is introduced.

The disclosure relates to an application device for applying an application medium onto a component, preferably for application of a coating onto a motor vehicle body component. The application device includes a print head for preferably serial and/or permanent application of the application medium, wherein the print head has: a nozzle plate, at least one nozzle in the nozzle plate in order to discharge the application medium, at least one valve element, which is movable relative to the nozzle plate, for control of the application medium discharge through the at least one nozzle, wherein the at least one movable valve element closes the at least one nozzle in a closing position and releases it in an opening position, and at least one drive for moving the at least one valve element. The application device is characterised in particular in that it includes at least one temperature control apparatus for reducing heating of the at least one drive during application of the application medium.

The present disclosure generally relates to an isolation device for use in processing systems. The isolation device has a body with an inlet opening disposed at a first end coupled to a processing system component such as a remote plasma source and outlet openings, for example two, disposed at a second end which are coupled to a processing system component such as a process chamber. Flaps disposed within the body are actuatable to an open position from a closed position or to a closed position from an open position, to selectively allow or prevent passage of a fluid from the processing system component coupled to the isolation device to the other processing system component coupled thereto.

A valve device includes: valves configured to control a flow of processing gases supplied to a process vessel; a housing in which first flow paths through which the processing gases flow are formed; a heat diffuser configured to cover the housing and diffuse heat of the housing; a heating part configured to cover the housing covered with the heat diffuser and heat the housing via the heat diffuser; a supply configured to supply a coolant to a second flow path formed between the housing and the heat diffuser; and a controller configure to control the heating part to heat the housing to a first temperature when a predetermined process is performed on a target substrate, and before a start of a cleaning process of the process vessel, control the heating part to stop heating of the housing and control the supply to supply the coolant to the second flow path.

A fluororesin diaphragm valve includes a valve portion, a sealing mechanism and an adjusting mechanism for the opening degree of the valve. The valve portion includes a valve body, a valve shaft, and a valve upper cover. The valve body includes a square portion, an annular portion, and a valve chamber. The sealing mechanism includes a diaphragm, an upper valve body, a tightening ring and an annular portion of the valve body. The adjusting mechanism is installed on the top of the valve upper cover. The sealing mechanism is installed in the annular portion and at the minimum diameter area of the annular portion, having annular lattice-shaped ribbed plates with horizontal openings to increase the structural strength of the diaphragm seal and improve the heat dissipation effect.

Artificial dense granules composed of a sterically stabilized liposome shell encapsulating a polyphosphate nanoparticle core are provided as are methods for their production and use in the treatment of a severe hemorrhagic event.

A method of warming a valve assembly includes receiving an exhaust flow through a first heat exchanger first inlet; heating a coolant received through a first heat exchanger second inlet with the exhaust flow; exhausting the exhaust flow through a first heat exchanger first outlet; and discharging heated coolant through a first heat exchanger second outlet towards a second heat exchanger assembly that is coupled to the valve assembly to heat the valve assembly.
