High Performance Butterfly Valve Features

  • A fully adjustable stem packing allows for 180 degree wrench clearance for adjustment.
  • Its capable of sealing against pressure and against vacuum without packing modification.
  • The interference fit design provides bidirectional tight shutoff.
  • The extended neck provides two inches of pipeline insulation.
  • The standard K-LOK flange surfaces are uninterrupted, which allows standard spiral wound gaskets to be used.
  • No travel stops are required, making adjustment and maintenance much easier.
  • An optional lay length is able to fit K-LOK in non-standard lay length requirements.
  • The rocker arm packing allows uneven tightening of gland bolts without side loading the system packing.
  • The Double offset disc design provides the disc with a camming effect that lifts the disc away from the seat, thereby reducing seat contact wear.
  • A fire safe seat configuration allows for bidirectional service and constant two-point seal of the metal and RTFE seat components. This allows partial burn of the seat without excessive leakage.
