The valve head is the part of a valve that makes contact with the valve seat to seal the flow of fluid, while the valve face is the specific surface area of the valve head that directly interfaces with the seat. The valve head typically includes the entire upper portion of the valve, including the face, which is often flat or shaped to ensure a tight seal. In summary, the valve head encompasses the entire upper section, whereas the valve face is just the sealing surface.
