The Aegis® CEV series valves are constructed of High Nickel Alloys and provide proven long term maintenance-free operation in hot, strong effect caustic evaporation processes as well as other processes involving salt slurry. The CEV valve was specifically engineered to eliminate the historical problems common with valves used in the Caustic Evaporation Process including: steam leakage, twisted stems, seat erosion/washout, and corrosion.
