A valve and seat set has a seal coupled to the valve body, the seal surface comprising irregularities to allow pressure to propagate in-between the mating surfaces when pressure from the inside of the valve is equal to, or greater than, pressure from the outside of the valve. This allows the seal to lift in response to minimal differential pressure in the intended flow direction (from inside the valve), while effectively sealing pressure in the reverse direction (from outside the valve).

A composite seal including multiple seal elements is disclosed along with corresponding methods and seal structures. In one embodiment, the composite seal may include a first, substantially annular seal element having an upper body portion, a neck portion, and an axial protrusion. The upper body portion includes opposing inclined surfaces extending toward the neck portion defining a first angle. The axial protrusion includes opposing inclined surfaces extending towards an axial end of the axial protrusion defining a second angle, wherein the first angle and the second angle are substantially similar. The composite seal may further include a second, substantially annular seal element having a mouth portion, a neck portion and a recess portion, wherein the axial protrusion is configured to be complementarily engaged with the recess portion in an interlocking manner.
