  • Features

    The series OXST/OAST features a self-sealing, maintenance-free sealing system with a custom-made O-ring arrangement and simultaneous use of at least three O-rings (four O-rings from DN150). This design has proven to ensure an extremely long service life. This flanged ball valve meets the highest quality requirements of the German Chemical Industry and is supplied with a hand lever (up to DN100) made of solid material with two travel stops to prevent inadmissible torsional forces. Alternatively, an investment-cast cranked hand lever is available.

    • ◾ Antistatic design as standard
    • ◾ Blowout-proof stem
    • ◾ Chambered body gasket
    • ◾ Free of non-ferrous metals
    • ◾ Modular hand lever design for manual stem extension
