What is API 602,BS 5352,ASME B16.34/B16.11/B1.20.1/B16.25 /B16.5 Forged Globe Valve
API 602,BS 5352,ASME B16.34/B16.11/B1.20.1/B16.25 /B16.5 forged steel globe valve is a shut-off valve that operates by moving the disc along the centerline of the seat to open or close the flow. The seat orifice changes proportionally with the disc travel. Pressure ratings range from ANSI Class 150LB to 2500LB, with nominal sizes from DN10 to 500 (NPS 1/2 to 36).
The valve adopts multiple connection methods including flanged, butt-weld, threaded, and socket-weld, with three bonnet designs: bolted, welded, and pressure self-sealing, complying with international standards such as GB/T12235, API602, and ASME B16.34.
Its sealing surfaces use Stellite cobalt-based hard alloy overlay welding technology, featuring reliable cutoff and low wear, making it suitable for water, steam, oils, and corrosive media with an operating temperature range of -29℃ to 550℃. Valve body materials include various forged steels such as A105 and F304, with actuation options including manual, pneumatic, and electric operation.
Installation requires 1.5 times the nominal pressure for strength testing and 1.1 times for tightness testing. Maintenance must be performed in the closed position to ensure lubrication effectiveness.
Widely used in petrochemical, power generation, and urban heating systems, it is particularly suitable for high-temperature and high-pressure pipeline media control.
