Setting pressure of safety valve

Set pressure refers to the predetermined pressure when the safety valve disc starts to open under operating conditions. It is the gauge pressure measured at the valve inlet. At this pressure, under the specified operating conditions, the force generated by the medium pressure to open the valve is balanced with the force that keeps the valve flap on the valve. At this pressure, a measurable opening height begins, and the medium assumes a continuous discharge state that can be perceived visually or audibly.
