Product Overview
The industrial-grade stainless steel welded globe valve is a high-performance marvel crafted for the most demanding industrial scenarios. Esteemed for its exceptional fluid control capabilities, it finds its application in a multitude of sectors, encompassing petroleum, chemical, power generation, and pharmaceuticals. Engineered from robust stainless steel with expertly welded connections, it promises superior sealing performance, unparalleled resistance to corrosion, and unmatched durability suited for high-pressure and high-temperature applications. This ensures precise flow regulation or complete shutoff, thereby safeguarding system safety and stability.
Structure & Materials
1.
Valve Body Material
- The valve's main body is meticulously crafted from premium-grade stainless steel variants such as 304, 316, and 316L, offering outstanding resistance to corrosion. This makes it ideally suited for handling acidic, alkaline, and high-purity media.
- For extreme conditions, specialized materials like duplex steel or Hastelloy® can be employed to ensure robust performance.
2. Welded Connections
- Butt-weld (BW) ends are meticulously designed in compliance with ASME B16.25 standards, ensuring a leak-free integration with existing pipelines. These connections are ideal for high-pressure and hazardous fluid systems, guaranteeing safety and efficiency.
3.Sealing Design
- The sealing surfaces are hard-faced, utilizing materials such as Stellite® coating for the disc and seat, providing exceptional resistance to wear and erosion, thereby significantly extending the valve's service life.
- The packing chamber is equipped with flexible graphite or PTFE seals, which are crucial in preventing stem leakage, especially under high temperatures and pressures.
4. Actuation Options
- Manual: Equipped with an ergonomic handwheel or gearbox, designed for ease of operation with low torque requirements and includes a position indicator for precision.
- Automated: The valve is fully compatible with electric or pneumatic actuators, offering options for 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: Efficiently handles water, steam, oils, corrosive chemicals, and liquefied gases, among others.
- Design Standards: Adheres to GB/T 12235 for reliability and performance.
Key Advantages
Extreme Condition Resilience: Designed with cryogenic treatment and high-temperature hardening, making it perfect for LNG or steam applications where resilience is key.
Zero-Leakage Assurance: Featuring a dual-seal design combining both metal and soft sealing, rigorously tested in accordance with API 598 standards to ensure safety in handling toxic or flammable media.
Longevity-Optimized: Incorporates an anti-blowout stem, self-lubricating bearings, and boasts minimal maintenance requirements, ensuring long-lasting performance.
Typical Applications
- Petrochemical: Essential for reactor inlet/outlet lines and high-pressure ethylene pipelines, delivering efficiency and reliability.
- Energy Sector: Perfect for nuclear steam systems and thermal power plant feedwater control, providing robust performance.
- Fine Chemicals: Ideal for transferring corrosive acids and alkalis, as well as maintaining pharmaceutical-grade purity systems.
- LNG Infrastructure: Specifically designed for cryogenic liquefied natural gas storage and transportation, ensuring safety and efficiency.
Installation & Maintenance Guidelines
- Ensure that media flow direction aligns with the valve's arrow marking ("low-in, high-out") to prevent any potential seal damage.
- Undertake post-weld stress relief and apply argon arc root welding to prevent intergranular corrosion, thus enhancing durability.
- Regularly inspect the stem packing and diligently tighten gland bolts to maintain optimal performance and reliability.
