High Performance Butterfly Valve



The Crane Nuclear Flowseal soft seated High Performance Butterfly Valve utilizes a patented seal which provides bi-directional bubble tight shutoff.

  • The use of a patented seat enables soft seat valves to offer a bi-directional bubble tight shutoff (zero leakages) as measured under applicable standards. This unique seat design creates a self-energized seal in vacuum-to-low pressure application
  • The soft seat is designed for high services with minimal wear and low torque. Seat replacement is a simple operation, requiring no special tools.
  • Optional bi-directional sealing
  • The high-performance butterfly valve is a double offset design
  • 360 degree sealing seat area
  • long life of seat due to early disengagement of the disc from seat
  • reduced torque figures compared to zero offset butterfly designs
  • Overtravel stop – prevent disc from rotating into the wrong quadrant
