Structure & Materials
1.
Valve Body Material
- The valve's main body is meticulously crafted from top-tier stainless steel varieties such as 304, 316, and 316L, ensuring exceptional resistance to corrosion. This makes it ideal for handling acidic, alkaline, and high-purity media, delivering reliable performance even in the most challenging environments.
- For extreme conditions, specialized materials like duplex steel or Hastelloy® are available, offering an additional layer of resilience and longevity.
2. Welded Connections
- Featuring butt-weld (BW) ends that comply with ASME B16.25 standards, these valves assure leak-proof integration into pipelines, making them indispensable in high-pressure and hazardous fluid systems.
3.Sealing Design
- The valves boast hard-faced sealing surfaces, such as Stellite®-coated discs and seats, which provide superior wear and erosion resistance, significantly extending the valve's service life.
- A packing chamber with flexible graphite or PTFE seals is incorporated to avert stem leakage, even under the strain of high temperatures and pressures.
4. Actuation Options
- Manual: Enjoy effortless control with ergonomic handwheel or gearbox operation, complete with low torque and a position indicator for precision management.
- Automated: Seamlessly integrates with electric or pneumatic actuators, enabling remote control and system integration for sophisticated operations.
Technical Specifications
- Nominal Diameter**: DN15 ~ DN100 (1/2"~4")
- Pressure: PN16
- Temperature Range: From cryogenic depths of -196°C to the scorching heights of +550°C, suitable for high-temperature steam.
- Media Compatibility: Versatile handling of water, steam, oils, corrosive chemicals, and liquefied gases, making these valves a multi-purpose solution.
- Design Standards: Adherence to GB/T 12235 ensures the highest quality and reliability.
Key Advantages
Extreme Condition Resilience: Designed for excellence, these valves are cryogenically treated and hardened for high-temperature applications like LNG and steam.
Zero-Leakage Assurance: Featuring a dual-seal design (metal + soft sealing) and rigorously tested per API 598, these valves provide ultimate security against leaks in toxic or flammable media.
Longevity-Optimized: Engineered with anti-blowout stems, self-lubricating bearings, and requiring minimal maintenance, these valves promise extended durability and performance.
Typical Applications
- Petrochemical: Essential for reactor inlet/outlet lines and high-pressure ethylene pipelines, ensuring smooth and efficient operations.
- Energy Sector: Designed for use in nuclear steam systems and thermal power plant feedwater control, where reliability is non-negotiable.
- Fine Chemicals: Ideal for the transfer of corrosive acids and alkalis, and maintaining pharmaceutical-grade purity in sensitive systems.
- LNG Infrastructure: Perfect for cryogenic liquefied natural gas storage and transportation, ensuring safety and effectiveness.
Installation & Maintenance Guidelines
- Align the media flow direction with the valve arrow marking ('low-in, high-out') to safeguard the seal from damage, ensuring optimal performance.
- Post-weld stress relief and argon arc root welding are recommended practices to prevent intergranular corrosion, prolonging valve life.
- Regularly inspect stem packing and tighten gland bolts to maintain peak functionality and efficiency.
