As shown in the image, it has an extended stem design. This design separates the valve's internal components from the pipeline's welded ends, effectively enhancing heat dissipation. It also reduces the impact of welding heat on the valve's internal seals and structural parts, ensuring stable operation under high - temperature and high - pressure conditions.
Crafted from high - strength forged steel (e.g., A105, 304 stainless steel). The forged steel material provides excellent pressure resistance, impact toughness, and structural integrity, enabling the valve to withstand harsh working environments with high pressure and frequent media flow changes.
Designed for high - pressure pipeline systems in industries such as petroleum, chemical, and power. It can reliably control the on - off of media (liquids, gases) under high - pressure conditions, preventing leakage and ensuring the safety and stability of the pipeline system.
The extended stem helps the valve adapt to high - temperature media environments. By increasing the distance between the internal components and the heat source (pipeline welding end), it reduces the temperature transfer to the valve's sealing and control parts, maintaining good sealing performance and operational reliability.

Widely used in petroleum refining, chemical production pipelines. In high - pressure, high - temperature processes (e.g., catalytic cracking, hydrogenation reaction), the extended - stem design ensures the valve's reliable operation, controlling media flow and ensuring process safety.
Applied in power plant steam pipelines, energy transmission systems. It can withstand high - pressure steam and other media, and the extended stem helps manage heat transfer, maintaining valve performance and contributing to the stable operation of power and energy facilities.
Complies with industrial valve standards (e.g., API 6D, GB/T) for high - pressure forged steel valves. These standards cover design, manufacturing, and testing, ensuring the valve meets requirements for structural safety, sealing performance, and pressure - bearing capacity in high - pressure applications.
Undergoes strict factory tests: high - pressure leakage tests (to verify no leakage under rated pressure), material mechanical property tests (ensuring forged steel meets strength and toughness standards), and stem extension performance tests (checking heat dissipation and structural stability). Manufacturers often hold ISO 9001 certification, guaranteeing consistent quality for critical industrial applications.
