ERV Yellow DN25-1000

The ERV Yellow rubber expansion joint is used for flexible connections in pipeline systems for petrochemical applications. It is suitable for use with

fuels, fuels with ethanol additives such as E85, DIN fuels with up to 50% aromatics and natural gas. The ERV Yellow is not suitable for liquefied Petrol Gas (LPG). The flanges of the ERV Yellow are rotatable and standard available in DIN PN10 and PN16. The operating temperature depends on the medium and ranges from -20 °C to +90 °C. The maximum working pressure is 16 bar, 10 bar for larger diameters.

Movements
The maximum movements for the ERV Yellow expansion joint stated below apply to the neutral length for operating temperatures up to +50 ºC and are not in combination (no lateral/axial movements simultaneously). The permissible movements are reduced by 25% for temperatures between +50 ºC and +70 ºC and by 40% for temperatures between +70 ºC and +90 ºC. Use of the optional vacuum ring leads to a reduction of 50%.
