Product Overview
Introducing the industrial-grade stainless steel welded globe valve, a paramount fluid control apparatus engineered for rigorous industrial conditions. Its versatility shines in pipeline systems across sectors like petroleum, chemical, power generation, and pharmaceuticals. Crafted from superior stainless steel with robust welded connections, it ensures unparalleled sealing performance, corrosion resistance, and endurance under high-pressure and high-temperature scenarios. This valve excels in delivering precise flow control and reliable shutoff, guaranteeing the safety and stability of your system.
Structure & Materials
1.
Valve Body Material
- The main body is meticulously crafted from high-grade stainless steel varieties (such as 304, 316, 316L), providing exceptional corrosion resistance suitable for handling acidic, alkaline, and high-purity media with ease.
- For extreme conditions, specialized materials like duplex steel or Hastelloy® are available, offering superior performance and durability.
2. Welded Connections
- Featuring butt-weld (BW) ends in compliance with ASME B16.25 standards, this valve ensures seamless, leak-free integration with pipelines. It is the ideal choice for high-pressure and hazardous fluid systems.
3. Sealing Design
- Equipped with hard-faced sealing surfaces (e.g., Stellite®-coated disc and seat), this design combats wear and erosion, significantly prolonging the valve's operational life.
- The packing chamber utilizes flexible graphite or PTFE seals to effectively avert stem leakage even under elevated temperatures and pressures.
4. Actuation Options
- Manual: Offers ergonomic handwheel or gearbox operation, requiring minimal torque and includes a position indicator for convenience.
- Automated: Fully compatible with electric or pneumatic actuators, facilitating remote control and seamless system integration.
Technical Specifications
- Nominal Diameter**: DN15 ~ DN100 (1/2"~4")
- Pressure: PN16
- Temperature Range: -196°C (cryogenic) to +550°C (high-temperature steam)
- Media Compatibility: Suitable for water, steam, oils, corrosive chemicals, liquefied gases, and more.
- Design Standards: Compliant with GB/T 12235
Key Advantages
Extreme Condition Resilience: This valve undergoes cryogenic treatment and high-temperature hardening, making it ideal for LNG or steam applications.
Zero-Leakage Assurance: Utilizing a dual-seal design (metal + soft sealing), it is rigorously tested per API 598 to ensure reliability with toxic or flammable media.
Longevity-Optimized: Features like an anti-blowout stem, self-lubricating bearings, and reduced maintenance needs contribute to its lasting performance.
Typical Applications
- Petrochemical: Perfect for reactor inlet/outlet lines and high-pressure ethylene pipelines.
- Energy Sector: Essential for nuclear steam systems and thermal power plant feedwater control.
- Fine Chemicals: Reliable for transferring corrosive acids/alkalis and maintaining pharmaceutical-grade purity systems.
- LNG Infrastructure: Indispensable for cryogenic liquefied natural gas storage and transportation.
Installation & Maintenance Guidelines
- Ensure media flow direction aligns with valve arrow marking ('low-in, high-out') to prevent potential seal damage.
- Conduct post-weld stress relief and utilize argon arc root welding to prevent intergranular corrosion effectively.
- Regular inspection of stem packing and tightening of gland bolts is recommended to maintain optimal performance.
