Abstract
Described is a valve face seal assembly. The assembly includes a moveable member, such as a poppet, and a seal having a sealing portion carried by the moveable member. A seat opposite the sealing portion of the seal has a transaxial seat face and an axial seat face extending axially toward the moveable member at an obtuse angle from the transaxial seat face. When the seal of the moveable member is brought into contact with the seat, a seal is formed with the transaxial seat face and with the axial seat face.
