Product Description

The ERV Rotex rubber expansion joint is used for flexible connections in pipeline systems for hot water, cooling water and hot air. It is not suitable for use with drinking water, oil-contaminated cooling water, oil-contaminated air and the continuous transport of steam. Its flanges are rotatable and standard available in DIN PN10 and PN16. The operating temperature depends on the medium and ranges from -40 °C to +130 °C. The maximum working pressure is 10 bar up to 100 °C, 6 bar up to 110 °C.

CONSTRUCTION

Movement
The maximum movements for the ERV Rotex expansion joint stated below apply to the neutral length for operating temperatures up to +70 ºC and are not in combination (no lateral/axial movements simultaneously). The permissible movements are reduced by 25% for temperatures between +70 ºC and +100 ºC and by 50% for temperatures between +100 ºC and +130 ºC. The use of the optional vacuum ring leads to a reduction of 50%.
