    A valve is a device or natural object that regulates, directs or

    controls the flow of a fluid (gases, liquids, fluidized solids, or

    slurries) by opening, closing, or partially obstructing various

    passageways. Valves are technically fittings, but are usually discussed

    as a separate category. In an open valve, fluid flows in a direction

    from higher pressure to lower pressure. The word is derived from the

    Latin valva, the moving part of a door, in turn from volvere, to turn,

    roll.


    The simplest, and very ancient, valve is simply a freely hinged flap

    which swings down to obstruct fluid (gas or liquid) flow in one

    direction, but is pushed up by the flow itself when the flow is moving

    in the opposite direction. This is called a check valve, as it prevents

    or "checks" the flow in one direction. Modern control valves

    may regulate pressure or flow downstream and operate on sophisticated

    automation systems.


    Valves have many uses, including controlling water for irrigation,

    industrial uses for controlling processes, residential uses such as

    on/off and pressure control to dish and clothes washers and taps in the

    home. Even aerosol spray cans have a tiny valve built in. Valves are

    also used in the military and transport sectors. In HVAC ductwork and

    other near-atmospheric air flows, valves are instead called dampers. In

    compressed air systems, however, valves are used with the most common

    type being ball valves.


    There are many valve designs, types and models, with a wide range of

    industrial applications, such as [url=http://www.nbyxpc.com/solenoid-

    [/url], etc. All satisfy one or more of the functions identified above.

    Valves are expensive items, and it is important that a correct valve is

    specified for the function, and must be constructed of the correct

    material for the process liquid. Regardless of type, all valves have

    the following basic parts.. the body, bonnet, trim (internal elements),

    actuator, and packing. The basic parts of a valve are illustrated in

    the image on the right.


    [b]Valve Body[/b]
    The valve body, sometimes called the shell, is the primary boundary of

    a pressure valve. He serves as the main element of a valve assembly

    because it is the framework that holds all the parts together. The

    body, the first pressure boundary of a valve, resists fluid pressure

    loads from connecting piping. It receives inlet and outlet piping

    through threaded, bolted, or welded joints. The valve-body ends are

    designed to connect the valve to the piping or equipment nozzle by

    different types of end connections, such as butt or socket welded,

    threaded or flanged. Valve bodies are cast or forged in a variety of

    forms and each component have a specific function and constructed in a

    material suitable for that function.


    [b]Valve Bonnet[/b]
    The cover for the opening in the body is the bonnet, and it is the

    second most important boundary of a pressure valve. Like valve bodies,

    bonnets are in many designs and models available. A bonnet acts as a

    cover on the valve body, is cast or forged of the same material as the

    body. It is commonly connected to the body by a threaded, bolted, or

    welded joint. During manufacture of the valve, the internal components,

    such as stem, disk etc., are put into the body and then the bonnet is

    attached to hold all parts together inside.


    In all cases, the attachment of the bonnet to the body is considered a

    pressure boundary. This means that the weld joint or bolts that connect

    the bonnet to the body are pressure-retaining parts. Valve bonnets,

    although a necessity for most valves, represent a cause for concern.

    Bonnets can complicate the manufacture of valves, increase valve size,

    represent a significant cost portion of valve cost, and are a source

    for potential leakage.


    [b]Valve Trim[/b]
    The removable and replaceable valve internal parts that come in contact

    with the flow medium are collectively termed as Valve trim. These parts

    include valve seat(s), disc, glands, spacers, guides, bushings, and

    internal springs. The valve body, bonnet, packing, et cetera that also

    come in contact with the flow medium are not considered valve trim. A

    Valve's trim performance is determined by the disk and seat

    interface and the relation of the disk position to the seat. Because of

    the trim, basic motions and flow control are possible. In rotational

    motion trim designs, the disk slides closely past the seat to produce a

    change in flow opening. In linear motion trim designs, the disk lifts

    perpendicularly away from the seat so that an annular orifice appears.


    Valve trim parts may be constructed of assorted materials because of

    the different properties needed to withstand different forces and

    conditions. Bushings and packing glands do not experience the same

    forces and conditions as do the valve disc and seat(s). Flow-medium

    properties, chemical composition, pressure, temperature, flow rate,

    velocity and viscosity are some of the important considerations in

    selecting suitable trim materials. Trim materials may or may not be the

    same material as the valve body or bonnet.
