API Forged Self Sealing Globe Valve
This API forged self-sealing globe valve is designed for flow control and shut-off in high-temperature and high-pressure applications. The forged steel body provides excellent structural strength and reliability under severe service conditions. The pressure-assisted self-sealing bonnet eliminates the need for conventional gaskets, ensuring enhanced sealing performance. With precise throttling capability, the valve is widely used in steam systems, power plants, and energy facilities.

Structural Characteristics of
The valve body is made of high-quality forged steel with dense structure and high strength, suitable for high-temperature and high-pressure applications in small-bore piping systems.
The pressure seal structure improves sealing performance as system pressure increases, ensuring excellent tightness under high-pressure conditions.
The disc moves linearly along the seat centerline, providing accurate flow regulation along with reliable shut-off performance
The sealing surfaces are precision machined or hardened, providing excellent resistance to erosion and wear for long service life.
The compact design makes it ideal for installations in limited space and high-pressure small-diameter pipelines.
Suitable for water, steam, oil, gas, and other media, widely used in petroleum, chemical, power generation, refining, and high-pressure industrial systems.
