From the catalogue's introduction to this valve type: "T"-PATTERN GLOBE VALVES Low operation torque design. Self aligning two piece packing gland. High quality packing for reliable tightness and low emission performance. Rising and rotating stem for the most API 602 design simplicity. Outside Screw and Yoke (OS&Y). Standard construction of body-bonnet connections are bolted bonnet or welded bonnet type. Back-seat design. Standard gasket design for bolted-bonnet valves is spiral wound type up to class ASME 1500. Ring Joint gaskets are standard for ASME 2500 and above. SPW/RJ are available on request for all pressure classes as option. Full die forged structure for all pressure containing parts. Flanged valves are provided with flanges integral with the body forgings. The connection wire secures the disc to the stem, the disc can swivel in order to guarantee the complete contact between the disc and seats surfaces. Disc is machined to the tightest tolerances to ensure trouble free shutoff and cycling. GLOBE "T"-PATTERN VALVE DESCRIPTION Globe valves are used for flow regulation, frequent operation, increased flow resistance or for positive shut off when closed. Globe valves are closing-down valves in which the closure member is moved squarely on and off the seat. By this mode of disc travel, the seat opening varies in direct proportion to the travel of the disc. This proportional relationship between valve opening and disc travel is ideally suited for duties involving regulation of flow rate. Globe valves can also be used for on-off duty, the seating load can be positively controlled with high sealing capacity. The change in direction of fluid flow through these valves produces increased resistance and pressure drop. The standard Straight "T" Pattern valve body is the most common, but because of its tortuous flow passage it offers the highest resistance to flow of the patterns available. Globe valves are used in many industrial applications including the oil and gas industry, pharmaceutical, manufacturing, automotive, and marine. Globe valves are also recommended for services requiring frequent operation and positive shut off. High flow capacity port sizes and disc retraction minimize flow velocities and maximize valve service life. Standard seat design is screwed- in type for bolted bonnet and integral type for welded bonnet design. Extra thickness of the seat ring provides sufficient material to renew the seating surface over and over again.
