Dome Valve® Succeeds Where Others Fail at Lafarge From Fine Abrasive powders to Cohesive Materials At Lafarge’s Westbury Works in the UK, a complex arrangementof divertor valves is used to route highly abrasive cement powder to any of 10 storage silos. The life of the original manufacturer of valves was between 3 and 6 months.A12 month trial conducted by Lafarge indicated that ClydeDome Valves User options extend to the choice of ‘dome’, both in terms of rawmaterial and any surface coatings required.

® would last for approximately 2 years – in fact, thevalves were industrial still operating after four years – dramatically exceeding even the most optimistic of forecasts.Dome valves
1. Chrome or ENP – For sticky and abrasive materials2. ENP or Tungsten Carbide – For abrasive materials3. Industrial epoxy resin – For corrosive materials4. Reinforced PTFE – For food, sticky or wet materials ® have now been installed at other Lafarge plantsaround the world. These coatings can also be extended to the internal surfaces ofthe valve body and the adaptors.
