Butterfly valve seal retainer |
摘要 |
A butterfly valve comprises a butterfly vane including a radial notch. A seal groove is situated in the vane and a seal including tabs is disposed within the seal groove wherein the tabs are adapted to fit within the notch. The tabs are designed to bear against the sides of the notch. The notch is located on the high pressure side of the butterfly vane and in a position such that the butterfly housing limits the radial motion of the tabs when the valve is in the open position.
