The valve of a liquid fuel pressure regulator comprises a two-part construction consisting of a spherically contoured element and a stem. The spherically contoured element serves to swivelly mount the valve on the movable wall which carries the valve. The spherically contoured element comprises a hole which is on a radial to the center of the element. The shank of the stem is press-fitted to this hole to dispose the stem's flat circular head toward a seat with which the valve coacts as the pressure regulator operates. The swivel mounting compensates for misalignment and out-of-squareness of the valve travel relative to the seat and enables the head to close flat against the seat. Two embodiments are disclosed. In one, the spherically contoured element is a sphere and the hole is a blind hole drilled into the sphere. In the other, the spherically contoured element is a truncated sphere and the hole is a through-hole. Preferably the mounting includes a small spring for spring loading the valve within its mounting. In the one embodiment this spring bears against the sphere, and in the other, it bears against the distal end of the stem's shank.
