The valve seat has a sealing surface that extends past an outer perimeter of the tip and is sized to engage a valve ring of the fluid valve, the valve seat defining an annular space that permits radial movement of the valve ring relative to the axis of the stem to align with the valve ring as pressure is applied to the valve seat.
