KSB TRIODIS Valves

The KSB TRIODIS is a flexible metal seated Valve that provides tight shut off in Liquid Natural Gas (LNG) down to -254°C, Liquid Propane Gas (LPG), high temperature gas, and various other hydrocarbon services.

The KSB TRIODIS Valve utilizes a triple offset disc design, coupled with a flexible metal seat design which provides an independent static and dynamic seal. The valve is capable of achieving tight shut off at cryogenic temperatures, bi-directional sealing, and is fire-safe. Seat design allows for self-centering on the disc.
The use of an all metal seat design, allows the valve to withstand a partial or full burn in a fire condition. The all metal seat design provides a fire safe seal, all the time; and is not dependent on fire intensity. The KSB TRIODIS Valve is especially well suited for the natural gas industry, and excels in LNG applications.
