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 & Lightweight:45% reduction in weight and installation space compared to lug-type valves
Simplified Installation:Direct 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
