Design 

Shield^TM high performance Butterfly Valve's full-faced retainer is bolted to the body, locking the seat in the correct position. The seat is secured even without the mating flange.

The closely confined and well supported seat is energized by the disc and line pressure. The higher the pressure, the tighter the seal. In low pressure and vacuum applications, the energized seat offers superior sealing and longer service life than many other designs. Line media is sealed to zero-leakage in both directions.

Seat replacement is extremely easy. Just remove the seat retainer, rotate the disc into the closed position and place a new seat assembly in the machined recess of the body. This simple procedure will not disturb the disc or stem.
