The TRIODIS is a flexible metal seated valve that provides tight shut off in LNG (Liquid Natural Gas) down to -425 Degrees F, LPG (Liquid Propane Gas) , high temperature gas, and various other hydrocarbon services.

The TRIODIS valve utilizes a triple offset disc design, coupled with a flexible metal seat design which provides an independent static and dynamic seal. Seat design allows for self-centering on the disc. The valve is capable of achieving tight shut off at cryogenic temperatures, bi-directional sealing, and is fire-safe.

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.
