ABSTRACT:
A pressure release valve which includes a body having a cavity in the form of a frustum extending from a circular base and terminating in a circular opening at the top of the frustum. An annular lip extends perpendicularly from the circular opening toward the base of the body, the lip having a recessed annular shoulder. A central shaft extends axially through the circular opening in the body. A spindle head disc extends radially from the central shaft and has a circular edge seatable in the recessed annular shoulder. A top disc extends radially from the shaft, the top disc terminating in a downwardly extending flange spaced from the spindle head disc circular edge and spaced from the annular lip. Seals between the spindle head disc and the top disc provide a seal with the annular lip when the valve is in the closed position.
