Product Overview
The industrial-grade stainless steel welded globe valve is a high-performance fluid control device designed for demanding industrial environments. It is widely used in pipeline systems across industries such as petroleum, chemical, power generation, and pharmaceuticals. Constructed from stainless steel with welded connections, it delivers exceptional sealing performance, corrosion resistance, and high-pressure/high-temperature durability, enabling precise flow regulation or shutoff to ensure system safety and stability.
Structure & Materials
1.
Valve Body Material
- Main body crafted from premium stainless steel (e.g., 304, 316, 316L) for outstanding corrosion resistance, suitable for acidic, alkaline, and high-purity media.
- Specialized materials like duplex steel or Hastelloy® available for extreme conditions.
2. Welded Connections
- Butt-weld (BW) ends compliant with ASME B16.25 standards, ensuring leak-free integration with pipelines. Ideal for high-pressure and hazardous fluid systems.
3.Sealing Design
- Hard-faced sealing surfaces (e.g., Stellite®-coated disc and seat) for wear and erosion resistance, extending service life.
- Packing chamber with flexible graphite or PTFE seals to prevent stem leakage under high temperatures/pressures.
4. Actuation Options
- Manual: Ergonomic handwheel or gearbox operation with low torque and position indicator.
- Automated: Compatible with electric or pneumatic actuators for remote control and 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: Water, steam, oils, corrosive chemicals, liquefied gases, etc.
-Design Standards: GB/T 12235
Key Advantages
Extreme Condition Resilience: Cryogenic treatment and high-temperature hardening for LNG or steam applications.
Zero-Leakage Assurance: Dual-seal design (metal + soft sealing), tested per API 598 for toxic/flammable media.
Longevity-Optimized: Anti-blowout stem, self-lubricating bearings, and minimal maintenance requirements.
Typical Applications
-Petrochemical: Reactor inlet/outlet lines, high-pressure ethylene pipelines.
-Energy Sector: Nuclear steam systems, thermal power plant feedwater control.
-Fine Chemicals: Corrosive acid/alkali transfer, pharmaceutical-grade purity systems.
-LNG Infrastructure: Cryogenic liquefied natural gas storage and transportation.
Installation & Maintenance Guidelines
- Align media flow direction with valve arrow marking ("low-in, high-out") to prevent seal damage.
- Post-weld stress relief and argon arc root welding recommended to avoid intergranular corrosion.
- Regularly inspect stem packing and tighten gland bolts;
