Page 8 - Desalination technology

High operating pressures and extreme temperatures – wherever other valves reach their physical
limits, this series is the ideal solution. The double eccentric design of the valve disc, high-quality
materials and outstanding workmanship ensure safety even in extreme conditions of use. Diff erent
sealing systems enable an optimal solution for the respective fi eld of application.
