The opening pressure of a safety valve refers to the inlet pressure at which the valve disc begins to lift under operating conditions; at this pressure, a measurable lift height begins, and the medium is discharged continuously in a manner that can be detected visually or audibly.
The discharge pressure of a safety valve refers to the inlet pressure when the valve disc reaches the specified lift height.
