Abstract
A recessed seat retainer for a valve is secured in an annular recess on the face of a valve body by a totally internally disposed key system which does not create an external leak path. An annular keyway is formed in the cylindrical sidewall of a seat retainer. A key extends from the cylindrical sidewall of an annular recess formed in an axial face of the valve body. The key is received in the keyway and locks the retainer against axial dislodgement from the valve body.
