Replaceable Seat Butterfly Valve (Series 2200)

  • Stem design: Single piece shaft can be removed to service valve with no special tools required.
  • Top flange: Conforms to ISO 5211 for the mounting of a wide range of actuators, levers and gear operators.
  • One piece shaft: Maintains accurate disc position. The shaft is secured to disc with an accurately machined square broach – there are no shaft pins to create leakage paths or corrosion points.
  • Resilient seat surface: Extends past valve face to eliminates the need for gaskets on flanges.
  • Bi-directional secured seat: Seat is field replaceable, bi-directional and suitable for dead end service at the full rated pressure
  • Bushings: Five separate bushings provide correct alignment of shaft through the body and reduces operating torque.
  • Stem seal: Stem is sealed by two separate o-rings and an integral seal in the seat to ensure no external leakage for the life of the valve.
  • Disc edge: Smooth finished disc edge provides superior seal, reduces valve torque and provides bubble tight shutoff.
