Operating Pressure Range: 0.3 - 20 bargOperating Temperature Range: 0 - 220 °C NF6 Automatic Non-freeze Valve (Animation) Product Details NF6 Specifications Manual • Max. Operating Pressure: 20 barg• Max. Operating Temperature: 220°C• Helps prevent steam trap damage from freezing Always check the specification PDFs for the exact product specification available in your region. Benefits and Features Prevent Trouble from Freeze-up Automatically removes condensate from inside the trap to prevent damage to the trap from freeze-up of residual condensate. Easy to Use Compact size makes for simple installation. No adjustment necessary. Remains closed during equipment operation, automatically opening to discharge condensate using gravity after the shut-off of equipment. Built-in screen protects the valve from trouble caused by clogging. Application Areas Prevents damage to steam traps by preventing freeze-up.
