  • High-performance butterfly valve with double eccentric construction in order to separate the disc directly from the seat (gasket), thereby reducing friction and extending the service life
  • Continuous shaft with temperature resistant graphite bearing and PTFE gland packing for readjustment in operation for minimized leakage, even at low pressures
  • Antistatic fixture for ATEX area
  • Various actuator types can be selected
  • Bubble tight sealing, in accordance with EN 12266-1/P12, leak rate A
