The IMI TH Jansen Three-Lever Valve is a pure shut-off valve designed for high-frequency isolation of gaseous media in industries such as iron and steel, gas-fired power plants, air separation, and chemical processing. With low differential pressure handling (up to 200 mbar) and high static pressure resistance, it ensures reliable gas flow isolation. Available with internal (Type 440) or external (Type 450) shaft designs, it offers flexibility for various applications. Actuation options include manual worm gear, electric, hydraulic, or pneumatic operation, while multiple sealing types accommodate high-temperature and dust-laden environments.
