  • Features

    The series X-HT/A-HT is based on the TX/TA ball valve; with its pure graphite packing, it is specially designed for high temperature applications. The self-sealing, maintenance-free PTFE sealing system with custom-made preloaded Belleville spring 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 made of solid material with two travel stops to prevent inadmissible torsional forces.
