Resilient Butterfly Valves

  • Top Bushingacts as a bearing to support the shaft firmly as well as a weather seal to keep dust and moisture from entering the shaft housing
  • Mounting Flange designed to ISO 5211 to accommodate direct mounting of various actuator types without additional modification
  • Solid one piece through Shaftensures positive alignment of top and bottom support, ensuring low wear and tear
  • O-Ring provides secondary sealing of shaft to prevent fugitive emissions
  • Center Bushing provides additional shaft support allowing higher pressure drops with positive disc positioning without stressing seat seal ring. All shaft bushings provide smooth operation of valve without shaft seizure in body 
  • Hardened Taper Pins disc-to-shaft positive connection provides vibration-free operation without backlash. Field replaceable
  • Seat Face extends out and acts as flange
  • Phenolic-backed Seat is non-collapsible, stretch resistant, blow out proof and field replaceable
  • Disc is precision machined to an engineered contoured shape to provide bubble tight shutoff with smooth, low torque operation to minimize seat wear and prolong seat life
