ERV RED DN25-1000
ERV RED
The ERV Red rubber expansion joint is used for exible connections in
pipeline systems for hot water, drinking water (DVGW W270 and ACS
certied), hot cooling water and hot wastewater. This expansion joint is
also suitable for use with additives such as weak acids, alkalies, salt
solutions, technical alcohols, esters and ketone, and a wide range of other
chemicals. The ERV Red is not suitable for oil products. The anges of the
ERV Red are rotatable and standard available in DIN PN10 and PN16. The
operating temperatures depend on the medium and range from -40 °C to
+100 °C. The maximum working pressure is 16 bar or 10 bar for larger
diameters.

TECHNICAL DRAWING
MOVEMENTS
The maximum movements for the ERV Green 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%.
