Product Overview
The Industrial Welded Globe Valve by Wenzhou Safety Stainless Steel Co., Ltd. stands at the pinnacle of fluid control technology. Meticulously engineered for robust industrial applications, this valve is indispensable in pipeline systems within the petroleum, chemical, power generation, and pharmaceutical industries. Its stainless steel construction, paired with welded connections, ensures unmatched sealing efficiency, corrosion resistance, and exceptional performance under high-pressure and high-temperature conditions. This permits precise flow control or complete shutoff, safeguarding the operational integrity and stability of industrial systems.
Structure & Materials
1.
Valve Body Material
- The valve's main body is expertly crafted from top-grade stainless steel options such as 304, 316, and 316L, offering outstanding resistance to corrosion. This makes it highly suitable for handling acidic, alkaline, and ultra-pure media, ensuring your operations remain uncompromised.
- For extreme conditions, specialized materials like duplex steel or Hastelloy® are available, providing enhanced durability and performance.
2. Welded Connections
- The valve features butt-weld (BW) ends that adhere to ASME B16.25 standards, guaranteeing a flawless, leak-free integration with pipeline systems. This design is ideal for both high-pressure environments and hazardous fluid systems.
3.Sealing Design
- Incorporating hard-faced sealing surfaces, such as Stellite®-coated discs and seats, this valve offers superior resistance to wear and erosion, significantly prolonging its service life.
- The packing chamber is equipped with flexible graphite or PTFE seals, ensuring prevention of stem leakage even under extreme temperatures and pressures.
4. Actuation Options
- Manual actuation is achieved through an ergonomic handwheel or gearbox operation, featuring low torque requirements and a clear position indicator for ease of use.
- For enhanced functionality, the valve is also compatible with electric or pneumatic actuators, facilitating remote control and seamless system integration.

Key Advantages
Extreme Condition Resilience: Expertly designed to endure cryogenic treatment and high-temperature hardening, making it perfect for LNG and steam applications.
Zero-Leakage Assurance: Engineered with a dual-seal design (metal + soft sealing) and rigorously tested per API 598 standards, providing unmatched safety for handling toxic and flammable media.
Longevity-Optimized: Featuring an anti-blowout stem, self-lubricating bearings, and a minimal maintenance design, this valve is built for prolonged service life and efficiency.
Typical Applications
-Petrochemical: Suitable for reactor inlet/outlet lines and high-pressure ethylene pipelines.
-Energy Sector: Ideal for nuclear steam systems and thermal power plant feedwater control.
-Fine Chemicals: Expertly manages corrosive acid/alkali transfer and pharmaceutical-grade purity systems.
-LNG Infrastructure: Designed for cryogenic liquefied natural gas storage and transportation needs.
Installation & Maintenance Guidelines
- Ensure the alignment of media flow direction with the valve's arrow marking ("low-in, high-out") to prevent potential seal damage.
- Employ post-weld stress relief and argon arc root welding techniques to prevent intergranular corrosion, ensuring long-lasting durability.
- Regularly inspect stem packing and tighten gland bolts to maintain peak performance and safety.
