Industrial Valve Seat Material Comparison
| Material | Temperature Capability | Chemical Resistance | Leakage Performance | Performance Level | Typical Applications |
|---|---|---|---|---|---|
| PTFE | Up to 180°C | ★★★★★ | Class VI achievable | Standard | Chemical, water |
| RPTFE | Up to 200°C | ★★★★★ | Class VI achievable | Standard | Industrial valves |
| Filled PTFE | Up to 220°C | ★★★★ | Class VI achievable | Advanced | Higher cycle applications |
| PEEK | Up to 260°C | ★★★★ | Class VI achievable | Advanced | High pressure |
| Metal Seat | >300°C | ★★★ | Metal sealing | Severe Service | Extreme applications |
Notes: Bubble-tight shut-off (ANSI/FCI Class VI) can be achieved with suitable soft-seated designs under recommended operating conditions.
Soft Seat v.s. Metal Seat
| Soft Seat | Metal Seat | |
|---|---|---|
| Typical Materials | PTFE, RPTFE, PEEK | Stainless steel, alloys |
| Advantage | Tight shut-off | High durability |
| Temperature Capability | Medium range | Extreme temperature |
| Wear Resistance | Moderate | Excellent |
| Applications | Clean/corrosive media | Abrasive/high temperature service |
Notes: We recommend soft seat for tight sealing performance and chemical corrosion resistance. For longer service life, great wear resistance and stable performance under ultra-high or ultra-low temperatures, we suggest metal seat.
