Pneumatic eccentric butterfly valve

  • Port size:2″ to 100″,DN50-DN2400
  • Pressure:PN10-100 bar,150LB-900LB
  • Structure:Double eccentric or triple eccentric
  • Medium:Water,steam,oil,etc.
  • Temperature :-40~450℃
  • Body material:Ductile iron,carbon steel,stainless steel,etc.
  • Connection:Flanged,wafer,lugged and welded end
  • Feature:Double acting or single acting pneumatic actuator
Pneumatic eccentric butterfly valve can be double eccentric or triple eccentric structure with pneumatic actuator (single acting or double acting). Pneumatic eccentric butterfly valve is flanged, wafer, lug end connection eccentric butterfly valve,pneumatic actuator and solenoid valve, limit switch,air filter for automatic control. The pneumatic eccentric butterfly valve stem drive the valve corn rolling 90 in the body which can realize the full open or full close action.Pneumatic eccentric butterfly valve can according to the sealing performance into metal seal and soft seal with compact structure,small volume,reliable operation,good sealing,easy maintenance installation convenient and the adoptability is strong advantages.Stainless steel pneumatic butterfly valve can be widely used in petroleum,chemical industry,light industry,papermaking industrial,pharmaceutical,car automatic control system on a remote concentrated or local control.
