Product Introduction
PTFE High-Low Temperature Valve Seat
A specialized sealing component manufactured using polytetrafluoroethylene (PTFE) as the core material, engineered for extreme-temperature operating conditions.
Core Characteristics
- Broad Temperature Stability:
Long-term operating range: -200°C to 260°C;
Short-term tolerance: Up to 300°C (achieved via filled/modified materials). - Exceptional Corrosion Resistance:
Resists aggressive media including aqua regia, hydrofluoric acid, and organic solvents. - Self-Lubricating & Anti-Adhesion:
Friction coefficient as low as 0.04–0.15, eliminating external lubrication requirements. - High Insulation & Anti-Aging:
Dielectric strength: 10–19.7 kV/mm; weather-aging resistant.
Primary Applications
Deployed in critical systems including:
① Chemical valves
② Semiconductor equipment
③ Cryogenic engineering
④ Energy piping systems
Resolves sealing failures under extreme temperature/corrosion conditions, enhancing equipment reliability.
