PTFE Seated Butterfly Valve Features

  • Bi-directional valve with sealing capability to hold rated shut off pressure in either direction.
  • Circularly moulded back up elastomer provides uniform contact pressure over the entire seat without losing shaft bore shape, ensuring bubble tight closure every time.
  • Unique triple sealing system for shaft sealing, eliminates any fugitive emission or secondary leakage.
  • Self lubricated shaft bearings (PTFE coated stainless steel) for both drive end and non-drive end shaft ensures minimum bearing friction torque.
  • Live loaded disc shoulder sealing arrangement through pusher and disc springs in both top and bottom shaft bores, acting on PTFE liner ensures leak free mechanical stem seal.
  • Back up elastomer standardised in Viton to ensure excellent corrosion protection and maximum temperature resistance against media fumes and higher temperature.
  • Disc springs and fasteners standardised on corrosion resistant stainless steel to ensure long service.
  • A choice of exotic metallurgy for the disc, to meet any type of aggressive media.
  • Choice of liner materials of virgin PTFE or filled PTFE, which also extends on to the flange contact faces.
  • Low operating torque enables selection of smaller size actuators.
  • Perfect adaptability for conversion from manual to actuated operation due to standardized top flange.
