Abstract
A gate valve for use in oil field applications and including a seat seal assembly. The seat seal assembly includes primary, secondary, and tertiary seals for sealing the space between the seat rings and the valve body. The provision of multiple seals in the seat seal assembly provides redundancy that allows for maintenance of the seal between the components even if one or two of the individual seals fail.
