Technical Superiority & Innovation:

1. PTFE Lining Technology

  • Complete Media Isolation: Both seat and disc surfaces are fully encapsulated with virgin PTFE, providing comprehensive protection against acids, alkalis, and solvents across the full pH spectrum (0-14)  

  • Temperature Resilience: Maintains sealing integrity from -30°C to 180°C without degradation

2. Wafer Space Optimization

  • Compact & Lightweight45% reduction in weight and installation space compared to lug-type valves

  • Simplified InstallationDirect mounting between ANSI B16.5 or DIN EN 1092-1 flanges without additional hardware

  • Cost Efficiency: Lower material and installation costs while maintaining superior performance

3. Zero-Leakage Performance

  • Extended Service Life: PTFE-to-PTFE sealing ensures reliable operation for 50,000+ cycles in corrosive environments  

  • Bubble-Tight Sealing: Achieves EN 12266-1 Class A shutoff standards at 1.5×PN16 test pressure  

4. Maintenance-Free Operation

  • Self-Lubricating Design: PTFE surfaces provide natural lubrication, reducing operating torque by 40%  

  • Corrosion Immunity: Eliminates corrosion-related maintenance and replacement costs  

  • Quick Inspection: Split-body design option allows easy internal access without pipeline disconnection
