Structure & Materials
1.
Valve Body Material
- The main body is meticulously crafted from high-grade stainless steel options such as 304, 316, and 316L, ensuring exceptional corrosion resistance. Perfectly adaptable for environments dealing with acidic, alkaline, and high-purity media, guaranteeing longevity and reliability.
- For extreme conditions, specialized materials like duplex steel or Hastelloy® are available, providing robust solutions tailored to the most challenging industrial environments.
2. Welded Connections
- Features butt-weld (BW) ends that conform to ASME B16.25 standards. This compliance ensures a leak-free, seamless integration with your pipelines, ideal for high-pressure and hazardous fluid systems, enhancing operational safety.
3.Sealing Design
- Equipped with hard-faced sealing surfaces, such as Stellite®-coated discs and seats, this design offers exceptional wear and erosion resistance, significantly extending the service life of the valve even in the most abrasive conditions.
- The packing chamber is innovatively designed with flexible graphite or PTFE seals to effectively prevent stem leakage, even under extreme high temperatures and pressures, ensuring consistent and reliable performance.
4. Actuation Options
- Manual: Features an ergonomic handwheel or gearbox operation, offering low-torque handling with a clear position indicator for ease of use and precise control.
- Automated: Designed for seamless integration with electric or pneumatic actuators, enabling remote control capabilities and enhancing system integration for automated operations.
Technical Specifications
- Nominal Diameter**: Available in DN15 to DN100 (1/2" to 4") sizes, catering to a wide range of application needs.
- Pressure: Rated at PN16, ensuring robust performance in high-pressure environments.
- Temperature Range: Built to withstand temperatures from a cryogenic -196°C to a high of +550°C, perfect for applications involving high-temperature steam.
- Media Compatibility: Versatile compatibility with water, steam, oils, corrosive chemicals, and liquefied gases, making it a multi-functional choice for various industrial processes.
-Design Standards: Adheres to GB/T 12235 standards, ensuring quality and performance.
Key Advantages
Extreme Condition Resilience: Optimized through cryogenic treatment and high-temperature hardening, making it ideal for LNG and steam applications, where resilience against extreme conditions is paramount.
Zero-Leakage Assurance: Designed with a dual-seal system consisting of both metal and soft sealing elements, rigorously tested per API 598 standards to ensure zero leakage, even with the most toxic and flammable media.
Longevity-Optimized: Featuring an anti-blowout stem, self-lubricating bearings, and minimal maintenance requirements, this valve is engineered for durability and long-term performance.
Typical Applications
- Petrochemical: Specially suited for reactor inlet and outlet lines as well as high-pressure ethylene pipelines, providing reliable performance.
- Energy Sector: Essential for nuclear steam systems and thermal power plant feedwater control, delivering precise regulation and safety.
- Fine Chemicals: Ideal for transferring corrosive acids and alkalis, as well as ensuring pharmaceutical-grade purity in sensitive systems.
- LNG Infrastructure: Perfect for cryogenic liquefied natural gas storage and transportation, ensuring the integrity and safety of operations.
Installation & Maintenance Guidelines
- Ensure correct alignment of media flow direction with the valve's arrow marking ('low-in, high-out') to maintain seal integrity and prevent damage.
- Implement post-weld stress relief and argon arc root welding techniques to mitigate risks of intergranular corrosion, enhancing the longevity of the installation.
- Regularly inspect the stem packing and ensure gland bolts are tightened appropriately to maintain optimal performance and prevent leaks.
