A valve assembly comprises a valve stem, an annular bonnet configured to receive the valve stem, a valve disk coupled to one end of the valve stem, a seal, and an insert. The seal is disposed adjacent the valve disk and has a top surface and a bottom surface. The top surface includes a first pair of sealing ridges extending upwardly therefrom and the bottom surface includes a second pair of sealing ridges extending downwardly therefrom. The insert includes a recess configured to receive the seal that performs a sealing function and a biasing function. The valve assembly can easily be configured to open in either a clockwise or counterclockwise direction without resort to adapters or other additional pieces by rotating the bonnet/valve stem sub- assembly 90° relative to the insert.
