Product overview
The IMI Orton MV Cryogenic Series is a triple eccentric metal-seated valve engineered for LNG, cryogenic and extreme low-temperature applications. Its precision triple-offset geometry eliminates seal friction to deliver zero-leakage bi-directional shutoff. Designed for temperatures from -254°C to +426°C and produced in stainless steel, the valve complies with ASME, API 609 and relevant ISO standards and provides metal-to-metal sealing for fire-safe operation. The anti-blowout shaft increases safety and reliability. Sizes and pressure ratings are referenced on the site, with ports from 2″ to 160″ and maximum working pressures referenced up to 150 bar and up to 430 barg depending on configuration.
