Structure & Materials
1.
Valve Body Material
- The valve's main body is meticulously crafted from high-quality stainless steel, such as 304, 316, or 316L, ensuring superb corrosion resistance. It's ideal for handling acidic, alkaline, and high-purity media with ease.
- For extreme conditions, we offer specialized materials like duplex steel or Hastelloy®, providing additional robustness and reliability.
2. Welded Connections
- Our butt-weld (BW) ends adhere to ASME B16.25 standards, guaranteeing a leak-free, seamless integration with your pipelines. Perfectly suited for high-pressure environments and hazardous fluid systems.
3.Sealing Design
- Equipped with hard-faced sealing surfaces, such as Stellite®-coated discs and seats, this design excels in wear and erosion resistance, thereby significantly prolonging service life.
- The packing chamber features flexible graphite or PTFE seals, meticulously engineered to prevent stem leakage even under the most demanding high-temperature and high-pressure scenarios.
4. Actuation Options
- Manual: Features an ergonomic handwheel or gearbox operation, designed for low torque requirements and equipped with a position indicator for ease of use.
- Automated: Fully compatible with electric or pneumatic actuators, facilitating remote control and seamless system integration for enhanced operational efficiency.
Technical Specifications
- Nominal Diameter**: DN15 ~ DN100 (1/2"~4")
- Pressure: PN16
- Temperature Range: -196°C (cryogenic) to +550°C (high-temperature steam)
- Media Compatibility: This versatile valve is compatible with a wide range of media, including water, steam, oils, corrosive chemicals, and liquefied gases.
-Design Standards: GB/T 12235
Key Advantages
Extreme Condition Resilience: Our valves are fortified with cryogenic treatment and high-temperature hardening, making them the perfect choice for LNG and steam applications.
Zero-Leakage Assurance: Featuring a dual-seal design with both metal and soft sealing, our valves are rigorously tested per API 598 standards, ensuring safety and reliability with toxic or flammable media.
Longevity-Optimized: Designed with an anti-blowout stem and self-lubricating bearings, our valves demand minimal maintenance, promising an extended service life and reduced operational costs.
Typical Applications
- Petrochemical: Ideal for reactor inlet and outlet lines, as well as high-pressure ethylene pipelines.
- Energy Sector: Perfect for nuclear steam systems and thermal power plant feedwater control, ensuring reliable energy production.
- Fine Chemicals: Ensures safe transfer of corrosive acids or alkalis and maintains pharmaceutical-grade purity in systems.
- LNG Infrastructure: Reliable for handling cryogenic liquefied natural gas storage and transportation, ensuring secure and efficient operations.
Installation & Maintenance Guidelines
- Ensure the media flow direction matches the valve's arrow marking ('low-in, high-out') to protect against potential seal damage.
- We recommend post-weld stress relief and argon arc root welding to prevent intergranular corrosion, enhancing the valve's longevity.
- Regular inspections of the stem packing and tightening of gland bolts are essential practices for maintaining optimal valve performance.
