What is the difference between the reseating pressure and the sealing pressure of a safety valve?
Date: 2026-04-20Views: 419
The reseating pressure of a safety valve refers to the static pressure at the inlet when the valve disc comes back into contact with the seat after the valve has discharged, i.e., when the lift is reduced to zero.
The sealing pressure of a safety valve refers to the inlet pressure during a sealing test, at which the leakage rate across the sealing surface of the closing member is measured.
