BHAVYA Fluid Controls offer offset disc Butterfly Valves size from 3”(80NB) to 48”(1200NB) with various choice of Body, Disc & Seat Materials. Double-offset Butterfly valves also known by the name of High Performance Butterfly Valves, have the shaft mounted slightly offset from the pipe centerline, and the shaft is mounted behind the sealing band of the seat.  The seat is a narrow resilient band is clamped in the body and must be resilient.  PTFE or Elastomer (RUBBER) is resilient enough to seal, and the disc only wipes the seat for a few degrees of travel at seating. Metal seated Butterfly Valve also available for allowing operation to around 1200F.  As the disc is offset from the shaft, there is a lot of metal in the flow stream in the wide-open position, and double-offset valves have somewhat less maximum capacity than flat-disc, non-offset valves.
