Neotecha NeoSeal Lined Butterfly Valve with Manual Actuator

Neotecha NeoSeal Lined Butterfly Valve

• The elastomer back-up pads behind the liner ensure a tight fit around the disc, for a bubble tight shut-off.
• The liner provides a wide flange sealing surface.
• A one piece thin disc stem lined with 3 mm molded PFA providing high Kv values.
• The liner and disc are the only two valve parts in contact with the medium.
• Primary shaft sealing by preloaded contact between disc and liner hub.
• Secondary shaft seal by oversizing the shaft diameter in relation to the shaft hole in the liner.
• The liner and disc are molded and machined to close tolerances to provide:
  • low torque
  • less stress and deformation during opening and closing
• Vacuum tests with helium with pressures less than 20 Pa absolute (0.2 mbarA).
• Optional TFM lining available for extremely demanding applications.
• Integral body locating holes to ensure perfect centering of the valve.
• Actuator flange and stem dimensions acc. ISO 5211.
