From the catalogue's introduction to this valve type: "Y"-PATTERN GLOBE VALVES Low operation torque design. Rising and rotating stem for the most API 602 design simplicity. Outside Screw and Yoke (OS&Y). Flanged valves are provided with flanges integral with the body forgings. Standard construction of body-bonnet connections is welded bonnet type. Bolted bonnet is avaliable as alternative construction. Full die forged structure for all pressure containing parts. GLOBE "Y"-PATTERN VALVE DESCRIPTION Globe valves are used for flow regulation, frequent operation, increased flow resistance or for positive shutoff 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 oblique pattern globe- valve body is designed to reduce the flow resistance of the valve to a minimum. This valve combines low flow resistance for on-off duty with the robustness of globe-valve seatings. 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 shutoff. Pattern designed to reduce the flow resistance of the valve to a minimum. Self aligning two piece packing gland. 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. High quality packing for reliable tightness and low emission performance. Back-seat design. High flow capacity port sizes and disc retraction to minimize flow velocities and maximize valve service life. Body-guided disc for perfect seat and disc alignment. Disc is machined to the tightest tolerances to ensure trouble free shutoff and cycling. Standard seat design is integral type, screwed-in type is is avaliable as alternative construction or in case of bolted bonnet design. Extra thickness of the seat ring provides sufficient material to renew the seating surface over and over again.
