**Performance Features**
1. **Double Eccentric Design**:
- Two offsets (shaft and disc) reduce friction during operation, extending valve lifespan.
- Eliminates seat wear even after prolonged use.
2. **Stainless Steel Construction**:
- 316/304 stainless steel ensures resistance to corrosion, rust, and chemical erosion.
- Suitable for acidic, alkaline, and high-salinity environments.
3. **Bidirectional Sealing**:
- Zero-leakage performance in both flow directions (Class VI sealing per ANSI/FCI 70-2).
4. **High-Temperature Tolerance**:
- Operates reliably in temperatures ranging from **-40°C to 600°C** (-40°F to 1112°F).
5. **Low Torque Requirement**:
- Optimized disc geometry reduces actuation force, enabling cost-effective automation.
**Advantages**
- **Long Service Life**: Reduced wear due to double eccentricity lowers replacement frequency.
- **Cost-Efficient**: Minimal maintenance and energy savings from low-torque operation.
- **Versatility**: Compatible with liquids, gases, and semi-solid slurries.
- **Compact & Lightweight**: Saves space and simplifies installation compared to gate/globe valves.
- **API/ANSI Compliance**: Meets international standards for safety and performance.
**Application Scenarios**
- **Oil & Gas**: Pipeline isolation, refinery processes, LNG terminals.
- **Water/Wastewater**: Pump stations, desalination plants, stormwater management.
- **Chemical Processing**: Acid/alkali transfer, corrosive fluid control.
- **Power Generation**: Cooling systems, steam lines, turbine bypass.
- **Marine/Shipbuilding**: Seawater handling, ballast systems.
