Offset Disc Butterfly Valve

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.  

Butterfly Valve can be used in bi-directional pressure differential to prevent backflow in systems designed for unidirectional flow. Wafer Bonded/Renewable Seat Butterfly Valve no requirement of any gasket to mount between two flanges. BHAVYA Butterfly Valves are available with wider range of Elastomer Rubber Seat to suit various industrial applications with various operations. Wafer Butterfly Valves are also called by Center Disc Butterfly Valve or Slim Seal Design Butterfly Valve. Wafer Type Butterfly Valve also can be used for Flow Control Application or Shut-off purpose.
