What is the relationship between sealing pressure, sealing pressure ratio, and permissible sealing pressure?

For gate, globe, and check valves, as well as ball and butterfly valves, the sealing specific pressure qMF must be less than the sealing specific pressure q, and the sealing specific pressure is less than the sealing allowable specific pressure [q] (i.e., qMF < q < [q]).
